TPS3307-18-Q1 datasheet

 

Description :

The TPS3307-18-Q1, TPS3307-18 is a micropower supply voltage supervisor designed for circuit initialization primarily in automotive DSP and processor-based systems, which require more than one supply voltage. The TPS3307-18 is designed for monitoring three independent supply voltages: 3.3 V/1.8 V/adj,. The adjustable SENSE input allows the monitoring of any supply voltage >1.25 V. The various supply voltage supervisors are designed to monitor the nominal supply voltage as shown in the following supply voltage monitoring table.

TDA7438 Datasheet – Audio Processor

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
