Description

General part information

TDA7803A Series

The TDA7803A is a single chip quad bridge amplifier in advanced BCD technology integrating: a full D/A converter, digital input for direct connection to I2S (or TDM) and powerful MOSFET output stages.

The integrated D/A converter allows the performance to reach an outstanding 115 dB S/N ratio with more than 110 dB of dynamic range.

Moreover the TDA7803A integrates an innovative high efficiency concept, optimized also for uncorrelated music signals. The device is designed to be compatible to battery modulation for class-G systems.
