GENERAL DESCRIPTION
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.
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.
