Description
The TDA7348 is an upgrade of the TDA7318 audioprocessor. Thanks to the used BIPOLAR/CMOS technology, very low distortion, low noise and DC-stepping are obtained. Due to a highly linear signal processing, using CMOS-switching techniques  instead of standard bipolar multipliers, very low distortion and very low noise are obtained Several new features like softmute, zero-crossing mute and pause detector are implemented.

Features
● Input multiplexer
   – Three stereo and one mono inputs
   – Selectable input gain for optimal adaptation to different sources
● Volume control in 0.3db steps including gain up to 20dB
● Zero crossing mute and direct mute
● Pause detector with programmable threshold
● Soft mute controlled by software or hardware PIN
● Bass and treble control
● Four speaker attenuators
   – Four independent speakers control in 1.25dB steps for balance and fader facilities
   – Independent mute function
● All functions programmable via serial I2C bus
