SA576

Low power compandor

853-1536 18287

DESCRIPTION

The SA576 is a unity gain level programmable compandor designed

for low power applications. The SA576 is internally configured as an

expandor and a compressor to minimize external component count.

The SA576 can operate at 1.8V. During normal operations, the

SA576 can operate from at least a 2V battery. If the battery voltage

drops to 1.8V, this part will still continue to function, however, turning

external resistors is approximately 20k. A lower value can be used,

but the power consumption will go up.

The SA576 is available in a 14-pin plastic DIP and SO packages.
