DESCRIPTION
The TDA7512 is a high performance tuner circuit for
AM/FM car radio. It contains mixer, IF amplifier, de-
modulator for AM and FM, quality detection, ISS filter
and PLL synthesizer with IF counter on a single chip.
Use of BICMOS technology allows the implementa-
tion of several tuning functions and a minimum of ex-
ternal components.
