Intersil ISL21440IRTZ-T13

带电压基准CMOS，TTL200µs

Overview

The ISL21440IRTZ-T13 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 ISL21440IRTZ-T13 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 ISL21440IRTZ-T13 ideal for battery powered devices in battery level or low voltage monitor circuits.The ISL21440IRTZ-T13 is a pin-compatible, performance upgrade of the LTC1440, LTC1540, MAX921, and MAX931.
