GL 6551

COMPANDER

Description

The GL6551 is a compander IC to expand

dynamic

range

at

transmission/reception

systems and to improve the tone quality by

means of restricting noise. Two functions are

loaded on the IC, the one is the compressor

which has the 2/1 ratio of input/output ratio by

logarithm, and the expander which has the 1/w

ratio input/ output ratio by logarithm. The

GL6551equipped with input & filter Amp,

DATA IN OUT terminal. The GL6551 is well

suited for use in cellular radio MCA and handy

telephone set, radio communication systems.

Features

• Low operating supply voltage.

• Equipped with mute function and through function.

• Equipped with compressor MIC Amp and Expander

INPUT Amp

• Equipped with Filter Buffer Amp

• Equipped with DATA IN OUT terminal.

• Operation Voltage (2.4 ~ 7.0V)

• Total gain (10~ 100dB)
