LM4562 www.ti.com SNAS326K - AUGUST 2006 - REVISED DECEMBER 2013 LM4562 Dual High-Performance, High-Fidelity Audio Operational Amplifier Check for Samples: LM4562 FEATURES DESCRIPTION * * * * * The LM4562 is part of the ultra-low distortion, lownoise, high-slew-rate operational amplifier series optimized and fully specified for high-performance, high-fidelity applications. The LM4562 audio operational amplifiers deliver superior audio signal amplification for outstanding audio performance. The LM4562 combines extremely low voltage noise density (2.7nV/Hz) with vanishingly low THD+N (0.00003%) to easily satisfy the most demanding audio applications. To ensure that the most challenging loads are driven without compromise, the LM4562 has a high slew rate of 20V/s and an output current capability of 26mA. Further, dynamic range is maximized by an output stage that drives 2k loads to within 1V of either power supply voltage and to within 1.4V when driving 600 loads. 1 2 Easily Drives 600 Loads Optimized for Superior Audio Signal Fidelity Output Short Circuit Protection PSRR and CMRR Exceed 120dB (Typ) SOIC, PDIP, and TO-99 Packages APPLICATIONS * * * * * Ultra High-Quality Audio Amplification High-Fidelity Preamplifiers High-Performance Professional Audio High-Fidelity Active Equalization and Crossover Networks High-Performance Line Drivers and Receivers KEY SPECIFICATIONS * * * * * * * * * Power Supply Voltage Range: 2.5V to 17V THD+N (AV = 1, VOUT = 3VRMS, fIN = 1kHz) - RL = 2k: 0.00003% (typ) - RL = 600: 0.00003% (typ) Input Noise Density: 2.7nV/Hz (typ) Slew Rate: 20V/s (typ) Gain Bandwidth Product: 55MHz (typ) Open Loop Gain (RL = 600): 140dB (typ) Input Bias Current: 10nA (typ) Input Offset Voltage: 0.1mV (typ) DC Gain Linearity Error: 0.000009% The LM4562's outstanding CMRR (120dB), PSRR (120dB), and VOS (0.1mV) give the amplifier excellent operational amplifier DC performance. The LM4562 has a wide supply range of 2.5V to 17V. Over this supply range the LM4562's input circuitry maintains excellent common-mode and power supply rejection, as well as maintaining its low input bias current. The LM4562 is unity gain stable. This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF. The LM4562 is available in an 8-lead narrow body SOIC, an 8-lead PDIP, and an 8-lead TO-99.

This makes distortion measurements just slightly more difficult than simply connecting a distortion meter to the amplifier's inputs and outputs. The solution, however, is quite simple: an additional resistor. Adding this resistor extends the resolution of the distortion measurement equipment. The LM4562's low residual distortion is an input referred internal error. As shown in Figure 109, adding the 10 resistor connected between the amplifier's inverting and non-inverting inputs changes the amplifier's noise gain. The result is that the error signal (distortion) is amplified by a factor of 101. Although the amplifier's closed-loop gain is unaltered, the feedback available to correct distortion errors is reduced by 101, which means that measurement resolution increases by 101. To ensure minimum effects on distortion measurements, keep the value of R1 low as shown in Figure 109. This technique is verified by duplicating the measurements with high closed loop gain and/or making the measurements at high frequencies. Doing so produces distortion components that are within the measurement equipment's capabilities. This datasheet's THD+N and IMD values were generated using the above described circuit connected to an Audio Precision System Two Cascade. R2 1000: LM4562 R1 10: Distortion Signal Gain = 1+(R2/R1) + Analyzer Input Generator Output Audio Precision System Two Cascade Actual Distortion = AP Value/100 Figure 109. THD+N and IMD Distortion Test Circuit The LM4562 is a high-speed op amp with excellent phase margin and stability. Capacitive loads up to 100pF will cause little change in the phase characteristics of the amplifiers and are therefore allowable. Capacitive loads greater than 100pF must be isolated from the output. The most straightforward way to do this is to put a resistor in series with the output. This resistor will also prevent excess power dissipation if the output is accidentally shorted.
