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,
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.
Features
Absolute Maximum Ratings(Ta = 25
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 (V
must not exceed the values defined by the absolute maximum ratings.
