TDA7501

Line driver for digital car radio

Signal processor (DSPLD)

Features

■ Inputs:

– Quasi differential stereo input for CD

– Differential stereo inputs for phone,

navigation, FM, AM

– Single-ended input for cassette- four

independent input multiplexer and gain

stages

– Envelope-detector for AM noise-blanking

– Mixing of phone and navigation

– DC connection to DSP

– Dual MPX inputs

■ Outputs:

– 6 Output channels with independent

volume control

– 4 Main output channels with additional

input selector for phone and/or navigation

or CD

– Outputs level up to 4V rms

– AC connection from DSP

■ Digital control:

– SPI bus or I2C bus interface (selectable)

– Direct mute for the output stages and/or

high impedance mpx mute

Description

The line driver handles all analog input and output

signals for the digital car radio signal processor

TDA7501. The device contains four independent

input multiplexers to select the sources for the

DSP's four AD converters. Four additional gain

stages allow an adaptation to run the ADCs in

best S/N condition.

The six outputs have independent volume stages

with a large dynamic range. Using a 12V supply

the outputs are able to drive up to 4Vrms .
