The ADCMP341/ADCMP343 are two low power, high accuracy comparators with a 400 mV reference in an 8-lead SOT-23 package. Operating within a supply range of 1.7 V to 5.5 V, the devices only draw 6.5 μA (typical), making them ideal for low voltage system monitoring.
The ADCMP341 and ADCMP343 are low‑power, high‑accuracy dual comparators featuring a 400 mV reference and programmable hysteresis via a resistor string. They are supplied in an 8‑lead SOT‑23 package and operate from 1.7 V to 5.5 V, drawing only a few microamps of quiescent current, making them suitable for portable and low‑voltage applications.
The devices provide open‑drain outputs that support wired‑AND connections, with input bias currents as low as 5 nA. Detailed pin configurations, functional block diagrams, absolute maximum ratings, thermal characteristics, and ordering information are included in the document.
