ADCMP670

双路低功耗1.5 ％比较器，具有400 mV的参考 Dual Low Power 1.5% Comparator With 400 mV Reference

Product Details

The 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.

**Applications**

* Li-Ion monitoring

* Portable applications

* Hand-held instruments

* Window comparators

* LED/relay driving

* Optoisolator driving

* Control systems
