3 Description

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.
