Automotive Grade ±1.5°C 2.3V to 5.5V analog output temperature sensor with +10 mV/°C gain

The TMP23x -Q1 devices are a family of automotive grade precision CMOS integrated-circuit linear analog temperature sensors with an output voltage proportional to temperature , serving various automotive applications from powertrain to infotainment. These temperature sensors have a typical accuracy from 0°C to +70°C of ±0.5°C. The TMP235 -Q1 device provides a positive slope output of 10 mV/°C over the full –40°C to +150°C temperature range and a supply range from 2.3 V to 5.5 V. The higher gain TMP236 -Q1 sensor provides a positive slope output of 19.5 mV/°C from –10°C to +125°C and a supply range from 3.1 V to 5.5 V.

The 9-µA typical quiescent current and 800-µs typical power-on time enable effective power-cycling architectures to minimize power consumption for battery-powered devices. A class-AB output driver provides a strong 500-µA maximum output to drive capacitive loads up to 1000 pF and is designed to directly interface to analog-to-digital converter sample and hold inputs. With excellent accuracy and a strong linear output driver, the TMP23x -Q1 analog output temperature sensors are cost-effective alternatives to passive thermistors.
