TDA7348 - DIGITALLY CONTROLLED AUDIO PROCESSOR

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.

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. November 1994 1/14 This is advanced information on a new product now in development or undergoing evaluation. Details are subject to change without notice. 2/14 C10 2.2µF C14 100nF SM BOUT(L) 22 SPKR ATT 26 M.
