Monolithic Linear IC
LA8638V
Low-voltage Compander IC
for Cordless Telephones
Overview
The LA8638V provides dynamic range expansion, noise
suppression for enhancing the quality of audio signals in
cordless telephones and other communications systems.
This single chip provides the functions that make it ideal
for cordless telephones: a compressor with a logarithmic
compression ratio of 1/2, expander with a logarithmic
expansion ratio of 2, splatter filter, microphone amplifier,
BTL amplifier, waveform shaper for the receiving signal,
muting for both receiving and transmitting signals, and
standby operation.
speaker with a load of 2 k鈩?/div>
鈥?Standby operation that conserves battery power during
intermittent reception by disabling all but the waveform
shaper for the receiving signal
鈥?Built-in splatter filter with user-specified fc
鈥?Low-voltage operation (1.8 V to 5.5 V)
