The ISL21440 is a micropower, FGA reference, and comparator on a single chip. Drawing less than 6.5µA supply current across the full operating temperature range, the ISL21440 operates from a single 2V to 11V supply and can also be used with split bipolar supplies.
The ISL21440’s on-board reference provides a 1.182V ±0.5% output. It features programmable hysteresis and TTL/CMOS compatible outputs that sink and source current. Low bias currents permit high value divider resistors for typical circuit current drains of 2.5µA.
The low supply current makes the ISL21440 ideal for battery powered devices in battery level or low voltage monitor circuits.
The ISL21440 is a pin-compatible, performance upgrade of the LTC1440, LTC1540, MAX921, and MAX931.
