The AD22100 is a new monolithic silicon temperature sensor with several unique attributes. These attributes make it easier to interface the AD22100 to microcontrollers than other temperature sensor ICs. Available in both TO-92 and SOIC packages, the AD22100 features single-supply operation, the ability to measure negative temperatures without requiring a negative power supply, and a voltage output that is ratiometric to its power supply, rather than to an absolute voltage.
