CA3012 FM IF Wideband Amplifier

The CA3012 is an FM IF wideband amplifier with 3 limiter gain stages in a bipolar monolithic technology. The pin 1 input is an open base and has a separate feedback bias. The feedback bias pin, DC FB BYPASS, is externally bypassed and provides the means for a tuned coil input to the IF IN pin. The output is a high impedance open collector which may be matched to a tuned transformer, driving an FM detector. Internal regulation circuits provide DC bias to the gain stages and DC feedback circuit. The CA3012 is intended for FM limiting applications requiring high gain.
