Product speciﬁcation

Dual common-mode rejection differential

line receiver

TDA8578

FEATURES

• Excellent common-mode rejection up to high

frequencies

• Elimination of source resistance in the common-mode

rejection

• Few external components

• High supply voltage ripple rejection

• Low noise

• Low distortion

• Protected against electrostatic discharge

• AC and DC short circuit safe to ground and VCC

• Fast DC settling.

APPLICATIONS

• Audio

• Car radio.

GENERAL DESCRIPTION

The TDA8578 is a two-channel differential amplifier in a

16 pin DIL or SO package intended to receive line inputs

in audio applications requiring a high-level of

common-mode rejection. The amplifier has a gain of 0 dB

and a low distortion. The device is primarily developed for

those car radio applications where long connections

between signal sources and amplifiers (or boosters) are

necessary and ground noise has to be eliminated.
