描述

The TMP23x devices are a family of precision CMOS integrated-circuit linear analog temperature sensors with an output voltage proportional to temperature, making the series suitable for multiple analog temperature sensing applications. These temperature sensors are more accurate than similar pin-compatible devices on the market, featuring accuracy from 0°C to +70°C of ±1°C and ±2°C. The increased accuracy makes this series suitable for many analog temperature sensing applications. The TMP235 device provides a positive slope output of 10 mV/°C over the full –40°C to +150°C temperature range and a 2.3 V to 5.5 V supply range. The higher gain TMP236 sensor provides a positive slope output of 19.5 mV/°C from –10°C to +150°C and a 3.1 V to 5.5 V supply range.

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 well-suited to directly interface to analog-to-digital converter sample and hold inputs. With excellent accuracy and a strong linear output driver, the TMP23x analog output temperature sensors are excellent, cost-effective alternatives to passive thermistors.
