The 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 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. The device has excellent PSR, able to maintain accuracy over the entire supply range. With a fast conversion rate, low supply current, simple SPI compatible interface, and an enhanced operational temperature range it is ideal for a wide range of applications.

The TMP127-Q1 SPI interface features a simplified no register map protocol, with a read-only 3-Wire configuration and an optional read-write 4-Wire configuration. The TMP127-Q1 is a drop-in, software compatible replacement to the LM71 and is available in a small SOT package for close placement to heat sources and quick response times.
