TDA8575 Datasheet, PDF (2/16 Pages) NXP Semiconductors – Ground noise isolation amplifier

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.
