The TMP23x devices are a family of precision CMOS integrated-circuit linear analogtemperature sensors with an output voltage proportional to temperatureengineers can use in multiple analog temperature-sensing applications.These temperature sensors are more accurate than similar pin-compatibledevices on the market, featuring typical accuracy from0°C to +70°C of ±0.5°C.The increased accuracy of the series is designed for many analogtemperature-sensing applications.The TMP235 device providesa positive slope output of 10 mV/°C over the full –40°C to +150°C temperature range and a supplyrange from 2.3 V to 5.5 V. The higher gain TMP236A2DBZT sensor providesa positive slope output of 19.5 mV/°C from –10°C to +125°C and a supply range from 3.1 V to 5.5V.
The 9-μA typical quiescent current and 800-μs typical power-on time enable effectivepower-cycling architectures to minimize power consumption for battery-powered devices. A class-ABoutput driver provides a strong 500-μA maximum output to drive capacitive loads up to 1000 pF andis designed to directly interface to analog-to-digital converter sample and hold inputs. Withexcellent accuracy and a strong linear output driver, the TMP23xanalog output temperature sensors are cost-effective alternatives to passive thermistors.
