The ISL21440 is a micropower, FGA™ reference and comparator on a single chip. Drawing less than 1.8μA supply current over 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 monitors circuits.
The ISL21440 is a pin-compatible, performance upgrade of both the LTC1440, LTC1540, MAX921 and MAX931.
The price listed is the manufacturer's suggested retail price for quantities of 1K units. However, prices in today's market are fluid and may change without notice.
