CA3065 IC

From the shop's description

CA3065 IC The CA3065 IF Amplifier-Limiter, FM Detector, Electronic Attenuator, Audio Driver is a high-performance, monolithic integrated circuit specifically engineered for use as the complete sound system in television receivers. This highly integrated device consolidates several critical functions onto a single silicon chip, dramatically reducing the complexity and component count of the external circuitry required for a television’s sound intermediate-frequency (IF) subsystem. The core functional blocks within the IC include a multistage IF amplifier-limiter, which provides high-gain amplification and signal conditioning for the FM sound carrier Features: Electronic attenuator replaces the conventional volume control function. Volume control is accomplished by changing bias levels via an external variable resistor connected to Terminal 6, achieving attenuation in excess of 60dB. Differential peak detector requires only a single tuned coil for frequency demodulation. Internal Zener diode regulated power supply provides inherent high stability. Excellent AM rejection with a typical value of 50dB at 4.5MHz.
