LQFP44
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 .
