Low Voltage Compander  
Pin Configuration  
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

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.

Stress above those listed under “Absolute Maximum Rating” may cause permanent damage of device.  
This is stress rating only and functional operation of the device at these or any other conditions above  
those indicated in the operational sections of this specification is not implied.  
Exposure to absolute maximum rating conditions for longer periods may affect device reliability.  
During overload conditions (VIN > VCC or VIN <GND), those voltage on VCC pins with respect to ground  
must not exceed the values defined by the absolute maximum ratings.
