3 Description

The TMP75 and TMP175 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 analogto-

digital converter (ADC) offers resolutions down to

0.0625 °C. The devices are available in the industrystandard

LM75 SOIC-8 and MSOP-8 footprint.

The TMP175 and TMP75 feature SMBus, two-wire,

and I2C interface compatibility. The TMP175 device

allows up to 27 devices on one bus. The TMP75

allows up to eight on one bus. The TMP175 and

TMP75 both feature an SMBus Alert function.

The TMP175 and TMP75 devices are ideal for

extended temperature measurement in a variety of

communication, computer, consumer, environmental,

industrial, and instrumentation applications.

The TMP175 and TMP75 devices are specified for

operation over a temperature range of −40 °C to +125

°C.

The TMP75 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.
