www.DataSheet4U.com AGC-O in a CIC Size Hybrid GS3026 - DATA SHEET FEATURES CIC suitable package size 8:1 compression ratio 38 dB maximum system gain, adjustable over a 38 dB range output compression threshold, adjustable over 16 dB range designed to drive a class D integrated receiver averaging detector 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. STANDARD PACKAGING Hybrid typical dimensions: 0.162 in x 0.094 in x 0.070 in ...
