Receiver Subsystem General-Purpose Amplifier Array
CA3088E, monolithic integrated circuit, subsystem that provides converter, amplifier, detector, audio preamplifier stages receiver. CA3088E also provides internal first amplifier stage, delayed optional external amplifier, buffer stage drive tuning meter, terminals facilitating optional tone control. Figure functional diagram CA3088E. signal from low-noise converter applied first amplifier then coupled second amplifier. This signal then detected externally filtered. resultant audio signal applied audio preamplifier. Optionally, tone control circuit connected junction detector circuit audio preamplifier. gain first amplifier stage controlled internal circuit. CA3088E supplies delayed signal output with external amplifier. buffered output signal also available driving tuning meter. voltage, internally regulated Zener diode, supplies second amplifier, tuning meter circuits also used with other stage. CA3088E features four independent transistor amplifiers, each incorporating internal biasing temperature tracking. These amplifiers particularly useful generalpurpose amplifier, oscillator, detector applications wide variety equipment designs.
