Maxim DS1631/DS1631A/DS1731 Digital Thermometer Datasheet
The Maxim DS1631 family (DS1631, DS1631A, DS1731) are high‑precision digital thermometers and thermostats that communicate via a 2‑wire serial interface. They offer selectable resolution (9‑12 bits), wide supply voltage (2.7 V‑5.5 V) and operate over a temperature range of –55 °C to +125 °C.
The document provides ordering information, pin descriptions, electrical characteristics, register maps and example operation sequences for continuous‑conversion and one‑shot modes, as well as EEPROM specifications for non‑volatile configuration.
