Texas Instruments' TMP127-Q1 is a high-accuracy ±0.8°C digital temperature sensor that supports an ambient temperature range of -55°C to +175°C. The TMP127-Q1 features 14-bit signed temperature resolution (±0.03125°C per LSB) while operating from a 1.62V to 5.5V supply range. The device has excellent PSR and maintains accuracy over the entire supply range. Fast slew rates, low supply current, simple SPI-compatible interface, and enhanced operating temperature range make this device ideal for a variety of applications.
The TMP127-Q1 SPI interface features a simplified register-less map protocol with read-only 3-wire configuration and optional read/write 4-wire configuration. The TMP127-Q1 is a software-compatible drop-in replacement for the LM71 in a small SOT package that can be placed close to heat sources and can improve response time. and AEC-Q100 qualified for automotive grade applications
