DS1626 - High-Precision 3-Wire Digital Thermometer/Thermostat

General Description

The DS1626 and DS1726 digital thermometers/thermostats provide temperature measurements and stand-alone thermostat capability over a -55°C to +125°C range.

The DS1626 offers ±0.5°C accuracy from 0°C to +70°C and the DS1726 has ±1°C accuracy from -10°C to +85°C.

Key Features

  • Temperature Measurements Require No External Components Measure Temperatures from -55°C to +125°C (-67°F to +257°F) DS1626: ±0.5°C Accuracy from 0°C to +70°C DS1726: ±1°C Accuracy from -10°C to +85°C Output Resolution is User Selectable to 9, 10, 11, or 12 Bits Wide Power-Supply Range (2.7V to 5.5V) Convert Temperature to Digital Word in 750ms (max) Stand-Alone Thermostat Capability Thermostatic Settings are User Definable and Nonvolatile (NV) Data is Read/Written Through a 3-Wire Serial Interfa.

DS1626/DS1726 High-Precision 3-Wire Digital Thermometer and Thermostat www.maxim-ic.com DESCRIPTION The DS1626 and DS1726 digital thermometers/thermostats provide temperature measurements and stand-alone thermostat capability over a -55°C to +125°C range. The DS1626 offers ±0.5°C accuracy from 0°C to +70°C and the DS1726 has ±1°C accuracy from -10°C to +85°C. The resolution of the measured temperature is user selectable from 9 to 12 bits. Communication with the DS1626 and DS1726 is achieved through a 3-wire serial bus. The DS1626 and DS1726 offer thermostatic functionality with three dedicated thermostat outputs (THIGH, TLOW, and TCOM), and overtemperature (TH) and undertemperature (TL) user-programmable thresholds stored in on-chip EEPROM.
