On a single 5V supply, the output swings from 1V to 4V with a 100 load connected to 2.5V. Harmonic distortion is -70dB for a 5MHz, 2VP-P output driving a 100 load in a gain of -1. The LT1815/LT1816/LT1817 are manufactured on Linear Technology's advanced low voltage complementary bipolar process and are available in a variety of TSOT-23, SO, MSOP, SSOP and leadless DFN packages. APPLICATIONS n The LT(R)1815/LT1816/LT1817 are low power, high speed, very high slew rate operational amplifiers with excellent DC performance. The LT1815/LT1816/LT1817 feature higher bandwidth and slew rate, much lower input offset voltage and lower noise and distortion than other devices with comparable supply current. A programmable current option (LT1815 and LT1816A) allows power savings and flexibility by operating at reduced supply current and speed. The circuit topology is a voltage feedback amplifier with the slewing characteristics of a current feedback amplifier.

Note 4: Input offset voltage is pulse tested and is exclusive of warm-up drift. Note 5: Slew rate is measured between 2V at the output with 3V input for 5V supplies and 2VP-P at the output with a 3VP-P input for single 5V supplies. Note 6: Full-power bandwidth is calculated from the slew rate: FPBW = SR/2VP Note 7: This parameter is not 100% tested. Note 8: The LT1815C/LT1816C/LT1817C are guaranteed to meet specified performance from 0C to 70C and are designed, characterized and expected to meet the extended temperature limits, but are not tested at -40C and 85C. The LT1815I/LT1816I/LT1817I are guaranteed to meet the extended temperature limits. Note 9: Thermal resistance (JA) varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads. If desired, the thermal resistance can be substantially reduced by connecting Pin 2 of the TSOT-23, Pin 4 of the SO-8 and MS8, Pin 5 of the MS10 or the underside metal of the DD package to a large metal area. Note 10: A resistor of 40k or less is required between the ISET and V- pins of the LT1815S6 and the LT1816AMS. See the Applications Information section for information on selecting a suitable resistor.

LT1815/LT1816/ LT1817 require some attention to board layout. A ground plane is recommended and trace lengths should be minimized, especially on the negative input lead. Low ESL/ESR bypass capacitors should be placed directly at the positive and negative supply (0.01F ceramics are recommended). For high drive current applications, additional 1F to 10F tantalums should be added. The parallel combination of the feedback resistor and gain setting resistor on the inverting input combine with the input capacitance to form a pole that can cause peaking or even oscillations. If feedback resistors greater than 1k are used, a parallel capacitor of value: CF > RG * CIN /RF should be used to cancel the input pole and optimize dynamic performance. For applications where the DC noise gain is 1 and a large feedback resistor is used, CF should be greater than or equal to CIN. An example would be an I-to-V converter. Input Considerations The inputs of the LT1815/LT1816/LT1817 amplifiers are connected to the base of an NPN and PNP bipolar transistor in parallel. The base currents are of opposite polarity and provide first-order bias current cancellation. Due to variation in the matching of NPN and PNP beta, the polarity of the input bias current can be positive or negative. The offset current, however, does not depend on beta matching and is tightly controlled. Therefore, the use of balanced source resistance at each input is recommended for applications where DC accuracy must be maximized. For example, with a 100 source resistance at each input, the 800nA maximum offset current results in only 80V of extra offset, while without balance the 8A maximum input bias current could result in a 0.8mV offset contribution. The inputs can withstand differential input voltages of up to 6V without damage and without needing clamping or series resistance for protection. This differential input voltage generates a large internal current (up to 80mA), which results in the high slew rate. In normal transient closed-loop operation, this does not increase power dissipation significantly because of the low duty cycle of the transient inputs. Sustained differential inputs, however, will result in excessive power dissipation and therefore this device should not be used as a comparator. Capacitive Loading The LT1815/LT1816/LT1817 are optimized for high bandwidth and low distortion applications. They can drive a capacitive load of 10pF in a unity-gain configuration and more with higher gain. When driving a larger capacitive load, a resistor of 10 to 50 should be connected between the output and the capacitive load to avoid ringing or oscillation. The feedback should still be taken from the output so that the resistor will isolate the capacitive load to ensure stability. Slew Rate The slew rate of the LT1815/LT1816/LT1817 is proportional to the differential input voltage. Therefore, highest slew rates are seen in the lowest gain configurations. For example, a 5V output step in a gain of 10 has a 0.5V input step, whereas in unity gain there is a 5V input step. The LT1815/LT1816/LT1817 are tested for a slew rate in a gain of -1. Lower slew rates occur in higher gain configurations. Programmable Supply Current (LT1815/LT1816A) In order to operate the LT1815S6 or LT1816A at full speed (and full supply current), connect the ISET pin to the negative supply through a resistance of 75 or less. To adjust or program the supply current and speed of the LT1815S6 or LT1816A, connect an external resistor (RSET) between the ISET pin and the negative supply, as shown in Figure 1. The amplifiers are fully functional with 0 RSET 40k. Figures 2 and 3 show how the gain bandwidth and supply current vary with the value of the programming resistor RSET. In addition, the Electrical Characteristics section of the data sheet specifies maximum supply current and offset voltage, as well as minimum gain bandwidth and output current at the maximum RSET value of 40k. 181567fb 12 LT1815/LT1816/LT1817 APPLICATIONS INFORMATION Power Dissipation 5V - V+ The LT1815/LT1816/LT1817 combine high speed and large output drive in small packages. It is possible to exceed the maximum junction temperature specification (150C) under certain conditions. Maximum junction temperature (TJ) is calculated from the ambient temperature (TA), power dissipation per amplifier (PD) and number of amplifiers (n) as follows: LT1815S6 V- + ISET RSET 181567 F01 -5V Figure 1. Programming Resistor Between ISET and V- 250 VS = p5V TA = 25C GAIN BANDWIDTH (MHz) 200 RL = 500 150 RL = 100 Power dissipation is composed of two parts. The first is due to the quiescent supply current and the second is due to on-chip dissipation caused by the load current. The worst-case load induced power occurs when the output voltage is at one-half of either supply voltage (or the maximum swing if less than one-half the supply voltage). Therefore, PDMAX is: PDMAX = (V+ - V-) * (ISMAX) + (V+/2)2/RL or 100 PDMAX = (V+ - V-) * (ISMAX) + (V+ - VOMAX) * (VOMAX/RL) 50 Example: LT1816IS8 at 85C, VS = 5V, RL=100 0 10 100 1k 10k RSET PROGRAMING RESISTOR () 40k 181567 F02 Figure 2.

Supply Current vs RSET Programming Resistor PDMAX = (10V) * (11.5mA) + (2.5V)2/100 = 178mW TJMAX = 85C + (2 * 178mW) * (150C/W) = 138C Circuit Operation The LT1815/LT1816/LT1817 circuit topology is a true voltage feedback amplifier that has the slewing behavior of a current feedback amplifier. The operation of the circuit can be understood by referring to the Simplified Schematic. Complementary NPN and PNP emitter followers buffer the inputs and drive an internal resistor. The input voltage appears across the resistor, generating current that is mirrored into the high impedance node. Complementary followers form an output stage that buffers the gain node from the load. The input resistor, input stage transconductance and the capacitor on the high impedance node determine the bandwidth. The slew rate is determined by the current available to charge the gain node capacitance. This current is the differential input voltage divided by R1, so the slew rate is proportional to the input step. Highest slew rates are therefore seen in the lowest gain configurations. 181567fb 13 LT1815/LT1816/LT1817 SIMPLIFIED SCHEMATIC (One Amplifier) V+ BIAS CONTROL +IN R1 OUT -IN C ISET V- 181567 SS LT1815S6/LT1816AMS ONLY TYPICAL APPLICATIONS Two Op Amp Instrumentation Amplifier R5 220 R1 10k R2 1k R3 1k - 1/2 LT1816 - R4 10k - 1/2 LT1816 + VOUT + VIN + R4 * 1 R2 GAIN (c) (c)1 | | (c) R3 (c)(c) 2 R1 R3 R4 R2 R3 * 102 R5 TRIM R5 FOR GAIN TRIM R1 FOR COMMON MODE REJECTION BW = 2MHz 181567 TA03 181567fb 14 LT1815/LT1816/LT1817 TYPICAL APPLICATIONS Photodiode Transimpedance Amplifier 1pF 1pF 4.75k PHOTODIODE SIEMENS/ INFINEON SFH213 5V - LT1815 + -5V -5V 4.75k OUTPUT OFFSET 1mV TYPICAL BANDWIDTH = 30MHz 10% TO 90% RISE TIME = 22ns OUTPUT NOISE (20MHz BW) = 300VP-P 181567 TA04 0.01F 4MHz, 4th Order Butterworth Filter 232 274 47pF 22pF 232 665 VIN - 274 220pF 562 1/2 LT1816 + 470pF - 1/2 LT1816 + VOUT 181567 TA05 181567fb 15 LT1815/LT1816/LT1817 PACKAGE DESCRIPTION S5 Package 5-Lead Plastic TSOT-23 (Reference LTC DWG # 05-08-1635) 0.62 MAX 0.95 REF 2.90 BSC (NOTE 4) 1.22 REF 1.4 MIN 3.85 MAX 2.62 REF 2.80 BSC 1.50 - 1.75 (NOTE 4) PIN ONE RECOMMENDED SOLDER PAD LAYOUT PER IPC CALCULATOR 0.30 - 0.45 TYP 5 PLCS (NOTE 3) 0.95 BSC 0.80 - 0.90 0.20 BSC 0.01 - 0.10 1.00 MAX DATUM `A' 0.30 - 0.50 REF 1.90 BSC 0.09 - 0.20 (NOTE 3) NOTE: 1.
