Low power compandor

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
on the part at a V
CC
of 1.8V requires two external resistors to bring
V
REF
to half V
CC
. One resistor connects between V
CC
and V
REF
;
the other connects from V
REF
to ground. A typical value for these
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.
