Description

The DIA20903 is a dual, high precision comparator

with open-drain output. The device operates over a

wide range of supply voltages from 2.7 V to 36 V, the

current drain is independent of the supply voltage.

The DIA20903 holds a lower input offset voltage

(VOS = ±3.5 mV at TA = 25°C), making it suitable for

applications requiring precision. Featuring an

open-drain output stage with an external pull-up

resistor, its output can be connected to other

open-drain outputs to achieve wired-AND logic

relationships.

The DIA20903 is available in the Green SOIC-8 and

DFN-8 packages. It is specified over ambient

temperature range of -40°C to 125°C, which meets

the requirements of automotive applications.
