3 Description
The TMP100 and TMP101 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 ADC
offers resolutions down to 0.0625°C. The devices are
available in 6-Pin SOT-23 packages.
The TMP100 and TMP101 devices feature SMBus,
Two-Wire, and I²C interface compatibility. The
TMP100 device allows up to eight devices on one
bus. The TMP101 device offers an SMBus Alert
function with up to three devices per bus.
The TMP100 and TMP101 devices are ideal for
extended temperature measurement in a variety of
communication, computer, consumer, environmental,
industrial, and instrumentation applications.
The TMP100 and TMP101 devices are specified for
operation over a temperature range of −55°C to
125°C.
