TMP126中文资料具有 175°C 工作温度、CRC 和压摆率警报的 ±0.3°C SPI 温度传感器数据手册TI规格书

描述 Description

The TMP126 is a high 0.3 °C accuracy digital temperature that supports an ambient temperature range of –55 °C to 175 °C. The TMP126 features a 14-bit signed temperature resolution (0.03125 °C per LSB) while operating over a supply range of 1.62 V to 5.5 V. With a fast conversion rate, low supply current, and a simple 3-wire SPI compatible interface, the TMP126 is designed for a wide range of applications.

The TMP126 includes additional advanced features for increased reliability in harsh environments such as 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 along with fast response times.
