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