Product data sheet
1. General description
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 applications that require a high level of common-mode rejection. The
device is contained in an 8-pin Small Outline (SO) package.
2. Features and benefits
 Excellent common-mode rejection, up to high frequencies
 Elimination of source resistance dependency in the common-mode rejection
 Few external components
 High supply voltage ripple rejection
 Low noise
 Low distortion
 All pins protected against electrostatic discharge
 AC and DC short-circuit safe to ground and V_CC
 Fast DC settling
