Digitally controlled audio processor
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
SO-28

●
All functions programmable via serial I2C bus
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 the serial bus (bit D0, Mute Byte), or directly on pin 22 through an I/O line of the microcontroller Very low DC stepping is obtained by use of a BICMOS technology.
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
