TDA1083

One chip AM/FM radio with audio power amplifier

Temic Semiconductors 

TDA1083

Different dc voltages are developed at Pin 16 due to gain

spread of AM-IF-amplifier. To determine the value of

parallel resistance R8, at the output of the demodulator

Pin 8 for VS = 9 V, AM mode without signal, dc voltage

should be selected at Pin 16.
