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.
