GL6552 General Description

The GL6552 is a Compander IC, which contains two variable gain circuits configured for compressing and expanding the dynamicrange, 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.

GL6552 Maximum Ratings

Parameter	Symbol	Spec.	Unit	Remark
Supply Voltage	V_CC, _MAX	7	V
^{Power Dissipation}	P_D.MAX	600	mW
Operating Temperature	T_STG	-55 ~+150	``

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_IN > V_CCor V_IN<GND), those voltage on V_CC pins with respect to ground must not exceed the values defined by the absolute maximum ratings.

GL6552 Features

· Operating Supply Voltage: 2 ~ 6 V
· Built in ALC circuit
· Built in Mute logic circuit
· Easy gain control to use external component
