•
Digital Output: SMBus™, Two-Wire, and I2C
Interface Compatibility
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.

TMP100 Features Two Address Pins
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.
TMP101 Features One Address Pin and an
ALERT Pin
