Dual common-mode rejection
differential line receiver
TDA8579
FEATURES
GENERAL DESCRIPTION
• Excellent common-mode rejection, up to high
frequencies
The TDA8579 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) or dual in-line (DIP) package.
• 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.
