Monolithic Linear IC
LA8633V
Low-voltage, Low-current Compander
Overview
Package Dimensions
The LA8633V is a low-voltage, low-current compander IC
for battery-powered, cordless telephone applications.
The LA8633V features a good signal-to-noise ratio and a
high dynamic range at voice-signal frequencies. The out-

The LA8633V also features an FSK comparator for receiv-
ing FSK-modulated digital data, a microphone amplifier,
selectable intercom or telephone operation expander out-
puts, and an output mute control.
The LA8633V operates from a 1.8 to 6.0V supply and is
available in 24-pin SSOPs.
