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
