GS3044 General Description
The GS3044 CIC hybrid features AGC-O capability for low distortion output limiting with an active low cut filter in a package size suitable for CIC instruments. The circuit consists of an AGC preamplifier and output stage, capable of driving a class D integrated receiver. The compression control circuit, connected between the input and output of the AGC preamplifier, varies the current controlled resistance. It operates with an 8:1 compression ratio and uses an averaging detector with a time constant of 270ms, selected to provide optimal sound quality over a full range of sound and listening environments. The actual attack and release times are typically 40ms and 150ms respectively when the circuit is fully in the compression region of operation (measured times vary depending on gain and threshold settings).
The system gain, compression control and filter corner frequency can be adjusted by choosing three independent resistors or 100k trimmers. Maximum system gain is 38dB. It can be adjusted within a 38dB range. The output compression threshold can be adjusted within a 16dB range. The filter's corner frequency can be adjusted from 530Hz to 2kHz.
