The audioprocessor TDA7342 is an upgrade of the TDA731X audioprocessor family.
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, and zero-crossing mute are implemented. The soft Mute function can be activated in two ways:
Via serial bus (Mute byte, bit D0) Directly on pin 21 through an I/O line of the microcontroller
Very low DC stepping is obtained by use of a BICMOS technology.Key Features
- All functions programmable via serial I2C bus
- Four speaker attenuators
Four independent speakers control in 1.25dB steps for balance and fader facilities Independent mute function - Input multiplexer
Two stereo and one mono inputs One quasi differential input Selectable input gain for optimal adaptation to different sources - Volume control in 0.3dB steps including gain up to 20dB
- Fully programmable loudness function
- Bass and treble control
- Zero crossing mute, soft mute and direct mute
