TDA8579T - NXP

TDA8579T Dual common-mode rejection differential line receiver

The TDA8579T is a two channel differential amplifier with 0 dB gain and low distortion. The device has been primarily developed for car radio applications where long connections between signal sources and amplifiers (or boosters) are necessary and where ground noise has to be eliminated. The device is intended to be used to receive line inputs in audio appli.
