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 analog-to-
digital converter (ADC) offers resolutions down to
0.0625°C. The devices are available in the industry-
standard 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.
