TMP75 (ACTIVE)

Temperature Sensor with I2C/SMBus Interface in Industry Standard LM75 Form Factor & Pinout

Recommended alternative parts

  • TMP102  -  10uA, I2C Temp. Sensor in a 1.6x1.6mm SOT-563
  • TMP112  -  High accuracy +/-0.5C max version of TMP102
  • TMP75B  -  1.8V version of TMP75/LM75 with faster conversion rate

Description

The TMP75 and TMP175 devices are digital temperature sensors ideal for NTC and PTC thermistor replacement. The devices offer a typical accuracy of ±1°C without requiring calibration or external component signal conditioning. IC 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 the industry standard LM75 SOIC-8 and MSOP-8 footprint.

The TMP175 and TMP75 feature SMBus, Two-Wire, and I2C interface compatibility. The TMP175 device allows up to 27 devices on one bus. The TMP75 allows up to eight 8 on one bus. The TMP175 and TMP75 both feature an SMBus Alert function.

The TMP175 and TMP75 devices are ideal for extended temperature measurement in a variety of communication, computer, consumer, environmental, industrial, and instrumentation applications.

The TMP175 and TMP75 devices are specified for operation over a temperature range of –40°C to 125°C.
