Dual common-mode rejection differential
line receiver
Product specification
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 V_CC
• 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.
