TMP75AIDGKR

±1°C Temperature Sensor with I2C/SMBus Interface in Industry Standard LM75 Size and Pinout

describe

The TMP75 and TMP175 devices are digital temperature sensors that are ideal replacements for negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistors. The device provides ±1°C typical accuracy without calibration or external component signal conditioning. The device temperature sensor is a highly linear product and can know the temperature without complex calculations or table lookups. An on-chip 12-bit analog-to-digital converter (ADC) provides resolution down to 0.0625°C. Both devices are available in industry standard LM75 SOIC-8 and MSOP-8 packages.

The TMP175 and TMP75 are compatible with SMBus, two-wire and I2C interfaces. The TMP175 device allows up to 27 devices on a bus. The TMP75 allows up to 8 devices on a bus. Both TMP175 and TMP75 have SMBus alarm function.

The TMP175 and TMP75 devices are ideal for extended temperature measurements in a variety of communications, computer, consumer, environmental, industrial and instrumentation applications.

The TMP175 and TMP75 devices are specified over a temperature range of -40°C to +125°C.

The TMP75 production unit is fully NIST-traceable sensor tested and verified using ISO/IEC 17025 standard accredited calibration with NIST-traceable equipment. Added a paragraph at the end
