DESCRIPTION
The GS3026 CIC hybrid features AGC-O capability for low
distortion output limiting and offers a package size suitable
for CIC instruments. The circuit consists of a newly designed
AGC preamplifier and output stage, capable of driving the
class D integrated receiver. The compression control
circuit varies the current controlled resistance, connected
between the input and output of the AGC preamplifier. The
compression circuit operates with an 8:1 compression
ratio and uses an averaging detector with a time constant
of 270 ms, selected to provide optimal sound quality over
the full range of sound and listening environments. The
actual attack and release times are typically 40 ms and 150
ms respectively when the circuit is fully in the compression
region of operation (measured times will vary depending
on gain and threshold settings).
The system gain and compression control can be adjusted
by the choice of two independent resistors. Maximum
system gain is 38 dB and it can be adjusted within a 38 dB
range. The output compression threshold can be adjusted
within a 16 dB range.
