3 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.
