Texas Instruments TMP20

the tmp20 is a cmos precision analog output temperature sensor available in the tiny sot563 package. the tmp20 operates from 55c to +130c on a supply voltage of 2.7v to 5.5v with a supply current of 4a. operation as low as 1.8v is possible for temperatures between +15c and +130c. the linear transfer function has a slope of 11.77mv/c (typ) and has an output voltage of 1.8639v (typ) at 0c. the tmp20 has a 2.5c accuracy across the entire specified temperature range of 55c to +130c. the tmp20 4a (max) supply current limits self-heating of the device to less than 0.01c. when v+ is less than 0.5v the device is in shutdown mode and consumes less than 20na (typ). view all in datasheet
