描述 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 DSPs four AD converters. Four additional gain stages allow an adaptation to run the ADCs in best S/N condition.

特性 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
