Texas Instruments TMP126-Q1 SPI Temperature Sensor
Texas Instruments TMP126-Q1 SPI Temperature Sensor is a 0.25°C accuracy digital temperature that supports an ambient temperature range of –55°C to 175°C. The TMP126-Q1 features a 14-bit signed temperature resolution (0.03125°C per LSB) while operating over a supply range of 1.62V to 5.5V. With a fast conversion rate, low supply current, and a simple 3-wire SPI compatible interface, the TMP126-Q1 is designed for a wide range of applications.
The Texas Instruments TMP126-Q1 includes additional advanced features for increased reliability in harsh environments, such as an optional CRC checksum for data integrity, programmable alert limits, a temperature slew rate warning, and an enhanced operational temperature range. The device utilizes a NIST traceable factory calibration for guaranteed accuracy and comes in a small SOT package for close placement to heat sources and fast response times.
