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.
Features
• Low-voltage operation and low-power consumption.
• On-chip frequency-shifted keyed (FSK) comparator.
• On-chip microphone amplifier with audio limiter and mute
option.
• Expander output analog switch for telephone or intercom
operation.
• Low-power, standby mode.
• 1.8 to 6.0V supply.
• 24-pin SSOP

Note 1 : This IC enters mute mode when the pins 16 and 17 become low.
2 : Pin 6 is used as an output pin when 8 is high (=open), pin 5 is used as an output pin when pin 8 is low.
3 : FSK waveform shaper circuit becomes on when pin 9 is high.
4 : FSK waveform shaping polarity : outputs low in the positive cycle of signal.
