TDA6192
Functional Description
3.4 Circuit Description
The TDA6192 device combines an AGC amplifier, an output buffer to drive a
following demodulator IC , a delayed tuner AGC with take-over point adjust-
ment, and a low noise reference source VREF. The gain of the AGC amplifier
is controlled by an external voltage. VREF is used as a reference for the take-
over point adjustment of the tuner AGC voltage. TUNAGC is an open-collector
output.
