Temperature Switches

Analog Devices temperature switches monitor temperature and activate digital output when measurements exceed the trip point setting. To meet differing design needs, we provide pin selectable, factory set, and user programmable trip point setting options. With support for a wide range of operating temperatures and without the need for external calibration, our portfolio of temperature switches also enables swifter design and production with faster time to market.

Analog Devices temperature switches come in small, low count plastic packages, operate at low supply voltages down to 2.7 V, and are power optimized—consuming typically less than 100 μA of current.
