1.4V-Capable ±0.5°C Accuracy Digital Temperature Sensor in the Compact SOT-563 Package

1.4V-Capable ±0.5°C Accuracy Digital Temperature Sensor in the Compact SOT-563 Package - TMP112
 

Description

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.

The 1.6-mm × 1.6-mm SOT563 package is 68% smaller footprint than an SOT23 package. The TMP112 family features SMBus, two-wire and I2C interface compatibility, and allows up to four devices on one bus. The device also features an SMBus alert function. The device is specified to operate over supply voltages from 1.4 to 3.6 V with the maximum quiescent current of 10 µA over the full operating range.

The TMP112 family is designed for extended temperature measurement in communication, computer, consumer, environmental, industrial, and instrumentation applications. The device is specified for operation over a temperature range of –40°C to +125°C.

The TMP112 family production units are 100% tested against sensors that are NIST-traceable and are verified with equipment that are NIST-traceable through ISO/IEC 17025 accredited calibrations.
