TDA8578

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.

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.
