LOW VOLTAGE COMPANDOR
DESCRIPTION
TK10651 is a noise reduction IC developed mainly for
cordless phones. It is also used for voice and data
communications. It has a built-in compressor circuit to
increase the average modulation level and an expander
circuit to reduce the noise level. The expander restores the
original dynamics of the input signal. The result is a high
quality signal transmission with low noise. Among the
many functions included, analog switching of the input and
output signal is particularly useful in cordless telephones.
Separate data input and output are provided. The audio
signal path can be muted during data transmission. The
signal path used for data transmission bypasses the com-
pressor and expander circuits.
The TK10651 is available in the SSOP-20 (MFP20)
surface mount package.
