Description: Multi-Gain Analog Temperature Sensor

Features

* n Low 1.5V operation n Four selectable gains n Very accurate over wide temperature range of
* 50˚C to +150˚C n Low quiescent current n Output is short-circuit protected n Extremely small SC70 package n Footprint compatible with the industry-standard LM20 temperature sensor Key Specifications

Applications

* Two logic inputs, Gain Select 1 (GS1) and Gain Select 0 (GS0), select the gain of the temperature-to-voltage output transfer function. Four slopes are selectable:
* 5.5 mV/˚C,
* 8.2 mV/˚C,
* 10.9 mV/˚C, and
* 13.6 mV/˚C. In the lowest gain configuration (GS1 and GS0 both
