GENERAL DEscriptION

The SGM8773 is a dual, high precision differential voltage comparator optimized for high voltage operation. The device can operate from 2.8V to 36V single supply or from ±1.4V to ±18V dual power supplies. It consumes low supply current without being affected by the supply voltage. Input common mode voltage is 1.5V lower than +VS. The SGM8773 has a push-pull output structure without external pull-up resistors. This feature makes it a good choice for applications whose PCB sizes are limited.

The SGM8773 is available in Green SOIC-8 and TDFN-3×3-8L packages. The SGM8773 is specified over the extended -40℃ to +125℃ temperature range.
