Product details

Package and mounting

Its 55 MHz gain-bandwidth product and 20 V/µs slew rate give it the headroom for line-level audio processing, active filters, and preamp stages without rolling off the high end. The 100 µV typical input offset keeps DC errors low enough that you can skip the servo in many designs. Supply span from 5 V to 34 V means it runs on single +5 V digital rails or ±15 V analog supplies equally well — just watch the common-mode range if you go single-supply. The dual-channel layout in one 8-SOIC saves board space on stereo paths or multistage filters.

A 55 MHz gain-bandwidth product means the open-loop gain stays above 60 dB up to about 55 kHz — plenty for audio-band precision. The 20 V/µs slew rate handles full-swing 20 kHz signals without visible slew-induced distortion; you get clean transient response on square waves and fast edges. For a dual op-amp drawing 10 mA per channel, the power budget is reasonable for a line-level stage. Input bias current of 10 nA is low enough for most filter and summing applications, though not in the picoamp range of FET-input parts — keep that in mind if you are working with high-impedance sources above 100 kΩ.

Package, supply, and temperature — fit for the board

Surface-mount only — no through-hole variant on this order code. Supply voltage range of 5 V to 34 V gives you flexibility: a single +5 V digital rail works, as does ±15 V for traditional audio rails. The 26 mA output current per channel is enough to drive headphones or line-level loads directly, but not speakers — plan a buffer stage for low-impedance loads.

Frequently asked questions

What is the LM4562MA/NOPB audio op amp used for?

The LM4562MA/NOPB is a dual audio amplifier designed for signal paths where low distortion and wide bandwidth are needed — line-level audio processing, active filters, preamp stages, and stereo audio paths. Its 55 MHz gain-bandwidth and 20 V/µs slew rate suit it for high-fidelity audio applications.

Is there a drop-in replacement or equivalent for LM4562MA/NOPB?

The TLV9362IDDFR is a dual general-purpose op-amp with a similar 25 V/µs slew rate and 10.6 MHz GBW, but it is a different amplifier type (general purpose, not audio-optimized) and has a different offset voltage and supply range. Verify the full parametric fit before substituting.
