GENERAL DEscriptION

The SGM8771 is a single, high precision voltage comparator with a 1.225V voltage reference. The device optimized for high voltage operation from 2.8V to 36V single supply. It consumes low supply current without being affected by the supply voltage. Input common mode voltage is 1.5V lower than +VS. The SGM8771 has an open-drain output structure that needs external pull-up resistor. It also has a 1.225V voltage reference that saves external reference and reduces system cost.

The SGM8771 features low input offset voltage of 2.4mV (MAX). It is suitable for applications re precision.

The SGM8771 is available in Green SOIC-8 and TDFN-3×3-8L packages. It is operated over the -40℃ to +125℃ temperature range.
