LM4562

Texas Instruments · Operational Amplifier · SOIC-8

The LM4562 is a dual high-performance audio operational amplifier with low total harmonic distortion (0.00003%) and low input noise. Its wide bandwidth and high slew rate suit high-fidelity preamplifiers, active filters, tone controls, and line-driver stages in audio equipment.

Pinout

Pin Name Type Function
1 OUTPUT_A output Output of amplifier A. Low-impedance output stage capable of ±26 mA output current, driving loads as low as 600Ω. Swings to within 1.4V of the supply rails when driving 600Ω.
2 -IN_A input Inverting input of amplifier A. High-impedance input (differential Zin ≈ 30 kΩ; common-mode ≈ 1 GΩ). Input bias current 10 nA typical.
3 +IN_A input Non-inverting input of amplifier A. High-impedance input; common-mode input voltage range within (V−)+2.0V to (V+)−2.0V.
4 V- power_in Negative supply rail. Operates from ±2.5V to ±17V dual supply (or 5V to 34V single supply). Typical quiescent current 10 mA total for both amplifiers.
5 +IN_B input Non-inverting input of amplifier B. High-impedance input; common-mode input voltage range within (V−)+2.0V to (V+)−2.0V.
6 -IN_B input Inverting input of amplifier B. High-impedance input (differential Zin ≈ 30 kΩ). Input bias current 10 nA typical, input offset voltage 0.1 mV typical.
7 OUTPUT_B output Output of amplifier B. Low-impedance output stage capable of ±26 mA output current; short-circuit protected. Closed-loop output impedance ~0.01Ω at 10 kHz.
8 V+ power_in Positive supply rail. Operates from ±2.5V to ±17V dual supply. Absolute maximum total supply (V+ − V−) is 36V. Bypass with a local decoupling capacitor to ground.
