The TMP75-Q1 and TMP175-Q1 devices are digital temperature sensors ideal for negative temperature coefficient (NTC) and positive temperature coefficient (PTC) thermistor replacement. The devices offer a typical accuracy of ±1°C without requiring calibration or external component signal conditioning. Device temperature sensors are highly linear and do not require complex calculations or look-up tables to derive the temperature. The on-chip, 12-bit, analog-to-digital converter (ADC) offers resolutions down to 0.0625°C. The devices are available in the industry-standard, LM75, 8-pin SOIC and VSSOP footprint.

The TMP175-Q1 and TMP75-Q1 feature SMBus, two-wire, and I2C interface compatibility. The TMP175-Q1 device allows up to 27 devices on one bus. The TMP75-Q1 allows up to eight devices on one bus. The TMP175-Q1 and TMP75-Q1 both feature an SMBus alert function.

The TMP175-Q1 and TMP75-Q1 devices are ideal for extended temperature measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications. The TMP75-Q1 production units are 100% tested against sensors that are NIST-traceable and are verified with equipment that are NIST-traceable through ISO/IEC 17025 accredited calibrations.

The TMP175-Q1 and TMP75-Q1 devices are specified for operation over the temperature range of –40°C to +125°C.
