Intersil CA3088E
The CA3088E, a monolithic integrated circuit, is an AM subsystem that provides the converter, IF amplifier, detector, and audio preamplifier stages for an AM receiver. The CA3088E also provides internal AGC for the first IF amplifier stage, delayed AGC for an optional external RF amplifier, a buffer stage to drive a tuning meter, and terminals facilitating the optional use of a tone control. The signal from the low-noise converter is applied to the first IF amplifier and is then coupled to the second IF amplifier.| Part No. | CA3088E |

DESCRIPTION
Figure 2 is a functional diagram of the CA3088E. This IF signal is then detected and externally filtered. The resultant audio signal is applied to an audio preamplifier. Optionally, a tone control circuit may be connected at the junction of the detector circuit and the audio preamplifier. The gain of the first IF amplifier stage is controlled by an internal AGC circuit.
