Philips Semiconductors

Ground noise isolation amplifier

Preliminary specification

TDA8575

FEATURES

• High common mode rejection up to high frequencies

• Reduced dependency of common mode rejection on

source resistance

• Low distortion

• Low noise

• AC and DC short-circuit safe

• Few external components

• ESD protected on all pins.

GENERAL DESCRIPTION

The TDA8575(T) is a two channel amplifier with differential

input and single-ended output for use in car audio

applications. The differential amplifier has a gain of 0 dB,

a low distortion and a high common mode rejection. The

TDA8575T comes in a 16 pin SO package and TDA8575

comes in a 16 pin DIP package.

The TDA8575(T) is developed for those car audio

applications where long connections between signal

sources and amplifiers (or boosters) are necessary and

ground noise has to be eliminated.
