Description

The CA2111A provides a multistage wideband amplifierlimiter, a quadrature detector, and an emitter-follower output stage. This device is designed for use in FM receivers and in the sound IF sections of TV receivers. In addition, an output terminal is provided which allows the use of the amplifierlimiter as a straight 60dB wideband amplifier.

The CA2111A amplifier-limiter features the excellent limiting characteristic of 3 cascaded differential amplifiers. The quadrature detector requires only one coil in the associated outboard circuit and therefore, tuning is a simple procedure.

A unique feature of the CA2111A is its exceptionally low AFC voltage drift over the full operating-temperature range.
