The CD114CP is designed as one kind of FM intermediate frequency amplifier circuit that can be used in the sound equipment and FM receiver. The internal circuit is composed of the intermediate frequency amplifier, the amplitude limiting circuit, the frequency discriminating circuit, the AFC clamping circuit, the level detection circuit, the AGC driving circuit, the signal level display driver circuit, the voltage stabilization circuit and the squelch circuit. Features It has the squelch function, the squelch sensitivity is high, the good contact characteristics, the high signal-to-noise ratio and AM rejection ratio.It uses the double-tuned loop tuner, the distortion degree is low.The signal indication output is proportional to the input signal.It uses the delay automatic gain control output.16-pin dual-row DIP package.
