SA576D
DESCRIPTION
The SA576 is a unity gain level programmable pandor designed for low power applications. The SA576 is internally configured as an expandor and a pressor to minimize external ponent 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 VCC of 1.8V requires two external resistors to bring VREF to half VCC. One resistor connects between VCC and VREF; the other connects from VREF 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.
