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.
