The ADCMP341/ADCMP343 are two low power, high accuracy comparators with a 400 mV reference and programmable hysteresis. Supported applications include portable devices, Li-Ion battery monitoring, handheld instruments, LED/relay driving, optoisolator driving, and control systems.
The ADCMP341/ADCMP343 are dual low power, high accuracy comparators featuring a 400 mV reference and programmable hysteresis via a resistor string. They operate within a supply range of 1.7 V to 5.5 V with a typical quiescent current of 6.5 µA, making them ideal for portable applications and low voltage system monitoring. The devices include open-drain outputs that support wired-AND connections and are available in a small 8-lead SOT-23 package.
