Product Summary

The DS1631Z is a ±0.5℃ accuracy digital thermometer and thermostat. The DS1631Z digital thermometers provide 9, 10, 11, or 12-bit temperature readings over a -55℃ to +125℃ range. The DS1631Z thermometer accuracy is ±0.5℃ from 0℃ to +70℃ with 3.0V ≤ VDD ≤ 5.5V, and the accuracy is ±1℃ from -10℃ to +85℃ with 3.0V ≤ VDD ≤ 5.5V. The thermostat on all three devices provides custom hysteresis with user-defined trip points (TH and TL). The TH and TL registers and thermometer configuration settings of the DS1631Z are stored in NV EEPROM so they can be programmed prior to installation.
