TMPx75 Temperature Sensors Texas Instruments TMPx75 Temperature Sensors are digital temperature sensors that are ideal for NTC and PTC thermistor replacement. The devices offer a typical accuracy of ±1°C without requiring calibration or external component signal conditioning. IC temperature sensors are highly linear and do not require complex calculations or look-up tables to derive the temperature. The on-chip 12-bit ADC offers resolutions down to 0.0625°C. The TMPx75 features SMBus, Two-Wire, and I2C interface compatibility. The TMP175 device allows up to 27 devices on one bus and up to 8 on one bus. Each of the TMPx75 devices feature an SMBus Alert function. These devices are ideal for extended temperature measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications. TMPx75A-Q1 devices from Texas Instruments meet AEC-Q100 specifications for use in automotive applications.
