Temperature Sensors - Analog and Digital Output

digital temperature sensorSPISC7014-bitthermal alertCRClow power

TMP126NDCKR is a low-power 14-bit SPI temperature sensor for monitored systems requiring programmable thermal limits, an ALERT output, and operation up to 150°C.

Best for

  • SPI-connected thermal monitoring
  • Low-power temperature measurement
  • Programmable thermal-limit monitoring

Avoid if

  • A temperature rating above 150°C is required
  • Accuracy tighter than ±0.8°C over the full TMP126N range is required
  • A two-wire I²C interface is required

Check before use

  • Confirm thermal coupling between the SC70 package and the monitored heat source.
  • Select a conversion period compatible with update-rate and self-heating requirements.
  • Use the correct SIO connection method when interfacing with a conventional 4-wire SPI controller.
