The TMP102 device is a digital temperature sensor ideal for NTC/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 SOT-23 package. TheTMP102 device features SMBus™, two-wire andI2C 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 supplyvoltages from 1.4 to 3.6 V with the maximum quiescent current of 10 µA over the full operatingrange.
The TMP102 device is ideal 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 production units are 100% tested against sensors that are NIST-traceable andare verified with equipment that are NIST-traceable through ISO/IEC 17025 accreditedcalibrations.
