TDA7348 Datasheet - ST Microelectronics

TDA7348 DIGITALLY CONTROLLED AUDIO PROCESSOR

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. DIP28 SO28 ORDERING NUMBER: TDA7348 (DIP28) TDA7348D (SO28) Due to a highly linear signal processing, using CMOS-switching techniques .

TDA7348 DIGITALLY CONTROLLED AUDIO PROCESSOR PRODUCT PREVIEW 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 .

TDA7348 Features

* like softmute, zero-crossing mute and pause detector are implemented. The Soft Mute function can be activated in two ways: 1 Via serial bus (bit D0, Mute Byte) 2 Directly on pin 22 through an I/O line of the microcontroller Very low DC stepping is obtained by use of a BICMOS technology.
