Applications
The RC4580IPWG4 targets consumer and professional audio equipment including preamplifiers, mixing consoles, and active equalizer circuits requiring low distortion dual op-amp performance. Its 110 dB CMRR and low bias current make it well-suited for balanced audio interface stages and headphone driver circuits. The dual-channel configuration reduces BOM count and PCB area in stereo audio signal chains compared to using two single op-amps.

Frequently Asked Questions
What CMRR does the RC4580IPWG4 achieve, and how does this affect noise rejection in balanced audio circuits?
The RC4580IPWG4 delivers 110 dB typical common-mode rejection ratio, with a guaranteed minimum of 80 dB. This high CMRR effectively suppresses 50 Hz or 60 Hz hum and RF interference picked up on balanced audio cable runs of several meters, ensuring clean signal reproduction in professional audio systems.
How low is the bias current of the RC4580IPWG4, and does it enable driving high-impedance sources like condenser microphones?
The RC4580IPWG4 has a maximum bias current of 0.5 µA, which is low enough to interface with high-impedance signal sources such as condenser microphone capsules (typically 1 kΩ to 10 kΩ source impedance) without introducing significant voltage error from current-times-resistance offsets at the input.
Is RC4580IPWG4 a cost-effective alternative to NE5532 in dual op-amp audio preamplifier slots?
The RC4580IPWG4 uses the same dual op-amp SOIC-8 footprint as the NE5532 and offers comparable audio bandwidth. Its 110 dB CMRR exceeds typical NE5532 specs, making it a competitive substitute in stereo preamp PCBs where identical pin-for-pin replacement and low noise at audio frequencies up to 20 kHz are required.
