Description

The TMP100-Q1 and TMP101-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 ADC offers resolutions down to 0.0625°C. The devices are available in 6-Pin SOT-23 packages.

The TMP100-Q1 and TMP101-Q1 devices feature SMBus, Two-Wire, and I2C interface compatibility. The TMP100-Q1 device allows up to eight devices on one bus. The TMP101-Q1 device offers an SMBus Alert function with up to three devices per bus.

The TMP100-Q1 and TMP101-Q1 devices are ideal for extended temperature measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.

The TMP100-Q1 and TMP101-Q1 devices are specified for operation over a temperature range of −55°C to 125°C.
