Description
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:
1. Via serial bus (Mute byte, bit D0)
2. Directly on pin 21 through an I/O line of the microcontroller
Very low DC stepping is obtained by use of a BICMOS technology.
Features
■ Input multiplexer
– Two stereo and one mono inputs
– One quasi differential input
– Selectable input gain for optimal adaptation to different sources
■ Fully programmable loudness function
■ Volume control in 0.3dB steps including gain up to 20dB
■ Zero crossing mute, soft mute and direct mute
■ 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
