Overview
GL6552 GL6552 Low Voltage Compander General Descriptions The GL6552 is a Compander IC, which contains two variable gain circuits configured for compressing and expanding the dynamic range, and improving of S/N ratio of audio signal.
It consists of compressor, expander, Mic Amp, limiter, ALC(Automatic Level Control)and mute logic.
The compressor circuit has the 2/1 ratio of input/output ratio by logarithm, and the expander circuit by logarithm.
An internal, temperature stable bandgap reference provides the necessary precision voltage and current.
Applications include cordless telephone and most voice RF links.
• Operating Supply Voltage: 2 ~ 6 V • Built in ALC circuit • Built in Mute logic c...
