The RCA CA3065 Television Sound System is a monolithic integrated circuit that combines a multistage IF amplifier limiter, an FM detector, an electronic attenuator, a zener diode regulated power supply, and an audio amplifier-driver that is designed to directly drive an n-p-n power transistor or high-transconductance tube. Because the circuit is so inclusive, a minimum number of external components is required. The CA3065 with its advanced circuit design provides a high-performance multistage subsystem for the sound system of a television receiver. A particular feature of the CA3065 is the electronic attenuator which performs the conventional volume control function.
