 Description
The DIO20903 is a dual ,high precision comparator
with open-drain output. The device operate over a
wide range of supply voltages from 2.7 V to 36 V, the
current drain is independent of the supply voltage.
The DIO20903 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, the output can be connected to other
open-drain outputs to achieve wired-AND logic
relationships.
The DIO20903 is available in the Green SOIC-8,
MSOP-8, DIP-8, TSSOP-8, TSOT23-8 and
DFN2*2-8 packages. It is specified over ambient
temperature range of -40°C to 125°C, which meets
the requirements of industrial applications.
