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 or ±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 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 requiring

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.
