DESCRIPTION

· The TMP75 and TMP175 are digital temperature sensors designed to replace NTC and PTC thermistors.

· They offer a typical accuracy of ±1 °C without requiring calibration or external signal conditioning.

· The sensors are highly linear, eliminating the need for complex calculations or look-up tables.

· They feature a 12-bit ADC with resolutions down to 0.0625 °C.

· Available in industry-standard LM75 SOIC-8 and MSOP-8 packages.

· Compatible with SMBus, two-wire, and I2C interfaces.

· TMP175 supports up to 27 devices on one bus, while TMP75 supports up to eight.

· Both devices include an SMBus Alert function.

· Ideal for extended temperature measurement in various applications.

· Operates over a temperature range of −40 °C to +125 °C.

· TMP75 units are 100% tested against NIST traceable sensors.
