TDA7348 Digitally controlled audio processor

Features: Input multiplexerThree stereo and one mono inputsSelectable input gain for optimal adaptation to different sourcesVolume control in 0.3db steps including gain up to 20dBZero crossing mute and direct mutePause detector with programmable thresholdSoft mute controlled by software or hardware PINBass and treble controlFour speaker attenuatorsFour independent speakers control in 1.25dB steps for balance and fader facilitiesIndependent mute functionAll functions programmable via serial I2C bus  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. The Soft Mute function can be activated in two  ways, either via …
