Thermal resistance for the $.0. package is 131C/W. Note 2: The output current sink capability can be increased for large signal conditions by overdriving the inverting Input. This Is shown in the section on Typical Characteristics. Note $: This spec indicates the current gain of the current mirror which Is used as tha non-inverting Input, Note 4: Input Vee match between the non-inverting and the inverting Inputs occurs for a mirror current (non-inverting input current) of approximately 10 pA. This is therefore a typical design center for many of the application circuits. Note 5: Clamp transistors are included on the IC to prevent the Input voltages from swinging below ground more than approximately 0.3 Voc. The negative input currents which may result from large signal overdrive with capacitance Input coupling need to be externally limited to values of approximately 1 mA. Negative Input currents In excess of 4 mA will cause the output voltage to drop to a low voltage. This maximum current applies fo any one of the input terminals. If more than one of the input terminals are simultaneously driven negative emalier maximum currents are akowed. Common-mode current biasing can be used to prevent negative Input voltages: see for example, the Differentlator Circuit In the applications section. Note : These specs apply for 40C < Ta < +685C, unless otherwise stated. Wote 7: Human body model, 1.5 kf in series with 100 pF. Application Hints When driving elther input from a low-impedance source, a limiting resistor should be. placed In series with the input lead to limit the peak input current. Currents as large as 20 mA will not damage the device, but the current mirror on the non-inverting input will saturate and cause a loss of mir- ror gain at mA current levelsespecially at high operating temperatures. Precautions should be taken to insure that the power supply for the integrated circuit never becomes reversed in polarity or that the unit Is not inadvertently installed backwards ina test socket as an unlimited current surge through the result- ing torward diode within the IC could cause fusing of the internal conductors and result in a destroyed unit. Output short circuits elther to ground or to the positive pow- er supply should be of short time duration. Units can be destroyed, not as a result of the short circuit current causing metal fusing, but rather due to the large increase In IC chip dissipation which will cause eventual failure due to exces- sive junction temperatures. For example, when operating from a well-regulated +5 Vp power supply at Ta = 25C with a 100 kf shunt-feedback resistor (from the output to the inverting input) a short directly to the power supply will not cause catastrophic failure but the current magnitude will be approximately 50 mA and the junction temperature will be above Ty max. Larger feedback resistors will reduce the current, 11 MQ. provides approximately 30 mA, an open cir- cuit provides 1.3 mA, and a direct connection from the out- put to the non-inverting input will result in catastrophic fail- ure when the output is shorted to V* as this then places the base-emitter junction of the input transistor directly across the power supply. Short-circults to ground will have magni- tudes of approximately 30 mA and will not cause cata- strophic failure at Ta = 25C. Unintentional signal coupling from the output to the non-in- verting input can cause oscillations. This is likely only in breadboard hook-ups with long component leads and can be prevented by a more careful lead dress or by locating the non-inverting input biasing resistor close to the iC. A quick check of this condition is to bypags the non-inverting input to ground with a capacitor. High impedance biasing resis- tors used in the non-inverting input circuit make this input lead highly susceptible. to unintentional AC signal pickup. Operation of this amplifier can be best understood by notic- ing that Input currents are differenced at the inverting-input terminal and this difference current then flows through the external feedback resistor to produce the output voltage. Common-mode current biasing is generally useful to allow operating with signal tevets near ground or even negative as this maintains the Inputs biased at +Vpe. Internal clamp transistors (see note &) catch-negative Input voltages at ap- proximately 0.3 Voc but the magnitude of current flow has to be limited by the external input network. For operation at high temperature, this limit should be approximately 100 pA. This new Norton current-differencing amplifier can be used in most of the applications of a standard iC op amp. Performance as a DC amplifier using only a single supply is not as precise as a standard IC op amp operating with split supplies but is adequate in many tess critical applications, New functions are made possible with this amplifier which are useful in single power supply systems. For example, blasing can be designed separately from the AC gain as was shown in the inverting. amplifier," the difference integra- tor allows controlling the charging and the discharging of the integrating capacitor with positive voltages, and the fre- quency doubling tachometer" provides a simple circuit which reduces the ripple voltage on a tachometer output DC voltage. 3-623 LOVEINT/}O8SIW1/006EIN1/0062N1NATL SEMICOND (LINEAR) 22 D MM b501124 0048510 4 Open Loop Gain 1a Sox.
