GENERAL DESCRIPTION
The TDA8579 is a two channel differential amplifie 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) or dual in-line (DIP) package.

FEATURES
• 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 VCC
• Fast DC settling.
