Overview

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 output compression is given by VO=0.5log VI, and the expansion, by the inverse operation.

The LA8633V also features an FSK comparator for receiving FSK-modulated digital data, a microphone amplifier, selectable intercom or telephone operation expander outputs, and an output mute control.

The LA8633V operates from a 1.8 to 6.0V supply and is available in 24-pin SSOPs.
