Texas Instruments TMP127-Q1 SPI Temperature Sensor

Texas Instruments TMP127-Q1 SPI Temperature Sensor 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 1.62V to 5.5V. The device has excellent PSR, able to maintain accuracy over the entire supply range. It is ideal for various applications with a fast conversion rate, low supply current, simple SPI compatible interface, and an enhanced operating temperature range.

The Texas Instruments 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.
