GENERAL DEscriptION
The SGM8770 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 SGM8770 has an open-drain output structure that needs external pull-up resistor.
The SGM8770 is available in Green SOIC-8 and TDFN-3×3-8L packages. The SGM8770 is specified over the extended -40℃ to +125℃ temperature range.
