Texas Instruments  TMP102AQDRLRQ1

The TMP102-Q1 device is a digital temperature sensor ideal for NTC and PTC thermistorreplacement where high accuracy is required. The device offers an accuracy of ±0.5°C withoutrequiring calibration or external component signal conditioning. Device temperature sensors arehighly 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. TheTMP102-Q1 device features SMBus, two-wire, and I2C interfacecompatibility, and allows up to four devices on one bus. The device also features an SMBus alertfunction. The device is specified to operate over supply voltages from 1.4 V to 3.6 V with themaximum quiescent current of 10 µA over the full operating range.

The TMP102-Q1 device is designed for extended temperature measurement in a variety ofcommunication, computer, consumer, environmental, industrial, and instrumentation applications. Thedevice is specified for operation over a temperature range of –40°C to 125°C.

The TMP102-Q1 production units are 100% tested against sensors that are NIST-traceableand are verified with equipment that are NIST-traceable through ISO/IEC 17025 accreditedcalibrations.
