The TMP112 family of devices are digital temperature sensors designed for high-accuracy, low-power, NTC/PTC thermistor replacements where high accuracy is required. The TMP112A and TMP112B offers 0.5°C accuracy and are optimized to provide the best PSR performance for 3.3V and 1.8V operation respectively, while TMP112N offers 1°C accuracy. These temperature sensors are highly linear and do not require complex calculations or lookup tables to derive the temperature. The on-chip 12-bit ADC offers resolutions down to 0.0625°C.
