The ADCMP670 consists of two low power, high accuracy,

comparator and reference circuits in a 6-lead TSOT package.

The internal 400 mV reference provides the ability to monitor

low voltage supplies. The device operates on a supply voltage

from 1.7 V to 5.5 V and draws only 6.5 μA typical, making it

suitable for low power system monitoring and portable applica-

tions. Hysteresis is included in the comparators. The comparator

outputs are open-drain and the output can be pulled up to any

voltage up to 5.5 V. The output stage is guaranteed to sink

greater than 5 mA over temperature.

COMP A AND COMP B

The ADCMP670 is currently available in one model, the

ADCMP670-1. This model has one inverting input and one

noninverting input, making it suitable for use as a window

comparator. The device is suitable for portable, commercial,

industrial, and automotive applications.
