Key Features
- Dual voltage-feedback op-amp with 55 MHz gain-bandwidth product for high-speed audio and instrumentation
- 120 dB typical common-mode rejection ratio (CMRR) and 700 µV max input offset voltage for precision DC accuracy
- 72 nA max input bias current with fully compensated frequency response in an 8-pin PDIP package
Applications
LM4562NA is designed for high-fidelity audio preamplifiers, active crossover filters, and professional mixing console circuits where low noise and high linearity are critical. Its 55 MHz gain-bandwidth product and excellent CMRR of 120 dB make it equally effective in precision instrumentation front ends, medical sensor amplifiers, and data-acquisition signal conditioning. The 8-pin PDIP package simplifies prototyping and through-hole assembly for audio and industrial designs.

Frequently Asked Questions
How does LM4562NA's 120 dB CMRR benefit differential signal acquisition compared to standard op-amps?
With a 120 dB typical CMRR, LM4562NA rejects common-mode interference 1000 times better than a device at 60 dB CMRR, suppressing 50 Hz or 60 Hz power-line noise by a factor exceeding one million. This makes it ideal for differential inputs in medical ECG front ends, precision weighing cells, and industrial 4–20 mA loop receivers where ground loops are unavoidable.
For an audio preamplifier running on ±15 V rails, what gain-bandwidth does LM4562NA deliver and how does that constrain closed-loop bandwidth?
LM4562NA delivers a 55 MHz gain-bandwidth product. At a closed-loop gain of 10 V/V (20 dB), usable bandwidth reaches 5.5 MHz, which covers the full 20 Hz to 20 kHz audio band with more than 275 times headroom. This allows steep active filter designs without phase shift degrading stereo imaging.
When replacing an NE5532 in a through-hole design, does LM4562NA offer measurable noise improvement?
LM4562NA achieves a voltage noise density of approximately 2.7 nV/√Hz, roughly 30% lower than the NE5532's typical 5 nV/√Hz, audibly lowering the noise floor in high-gain phono stages or microphone preamps. Both devices share the 8-pin PDIP footprint, so the swap is pin-compatible with no PCB changes required.
