Part Number : TDA7438

Function : THREE BANDS DIGITALLY CONTROLLED AUDIO PROCESSOR

Package : SO28, DIP 28 Type

Manufacturers : STMicroelectronics

Pinouts :

TDA7438 datasheet

Description

The TDA7438 is a volume tone (bass, middle and treble) balance (Left/Right) processor for quality audio applications in car-radio and Hi-Fi Systems. Selectable input gain is provided. Control of all the
functions is accomplished by serial bus. The AC signal setting is obtained by resistor networks and switches combined with operational amplifiers. Thanks to the used BIPOLAR/CMOS Technology,
Low Distortion, Low Noise and DC stepping are obtained.

Features :

1. INPUT MULTIPLEXER
– 3 STEREO INPUTS
– SELECTABLE INPUT GAIN FOR OPTIMAL ADAPTATION TO DIFFERENT SOURCES
2. ONE STEREO OUTPUT
3. TREBLE, MIDDLE AND BASS CONTROL IN 2.0dB STEPS
4. VOLUME CONTROL IN 1.0dB STEPS
5. TWO SPEAKER ATTENUATORS:
– TWO INDEPENDENT SPEAKER CONTROL IN 1.0dB STEPS FOR BALANCE FACILITY
– -INDEPENDENT MUTE FUNCTION
6. ALL FUNCTION ARE PROGRAMMABLE VIA SERIAL BUS

TDA7375 amplifier datasheet

Description :

The TDA7375 is a new technology class AB car radio amplifier able to work either in DUAL
BRIDGE or QUAD SINGLE ENDED configuration. The exclusive fully complementary structure of the output stage and the internally fixed gain guarantees the highest possible power performances with extremely reduced component count. The on-board clip detector simplifies gain compression operation. The fault diagnostics makes it possible to detect mistakes during car radio set assembly and wiring in the car.
