Texas Instruments' TMP127-Q1 is a digital temperature sensor designed for a wide range of applications. The device offers high accuracy with a tolerance of ±0.8°C and supports an ambient temperature range of -55°C to +175°C, making it suitable for harsh environments. 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.
One of the key benefits of the TMP127-Q1 is its simplified SPI interface, which features a no-register map protocol. The device can operate in either a read-only 3-wire configuration or an optional read/write 4-wire configuration, depending on the system requirements. This flexibility makes it easy to integrate the sensor into existing designs.
The device has excellent power supply rejection (PSR) that ensures accuracy is maintained over the supply range. The fast conversion rate and low supply current make the TMP127-Q1 an ideal solution for applications that require high-speed operation and low power consumption.
Moreover, the TMP127-Q1 is a drop-in, software-compatible replacement to the LM71, offering an easy upgrade path for existing designs. The sensor is available in a compact 2.90 mm x 1.60 mm SOT-23 package that enables close placement to heat sources and quick response times.
In summary, the Texas Instruments TMP127-Q1 digital temperature sensor is a high-accuracy solution that offers a wide operating temperature range and a simple SPI-compatible interface. The device can operate in a read-only 3-wire configuration or an optional read/write 4-wire configuration to fit the system requirements. Its excellent PSR, fast conversion rate, low supply current, and small package make it an ideal choice for a variety of applications.
