19-1841; Rev 1; 9/01 9-Bit/12-Bit Temperature Sensors with I2C-Compatible Serial Interface in a SOT23 General Description Features The MAX6625/MAX6626 combine a temperature sensor, ¦ 9-Bit Temperature-to-Digital Converter (MAX6625) a programmable overtemperature alarm, and an I2C™- ¦ 12-Bit Temperature-to-Digital Converter (MAX6626) compatible serial interface into single compact packages. They convert their die temperatures into digital values ¦ Accuracy using internal analog-to-digital converters (ADCs). The ±1°C (TA = +25°C) result of the conversion is held in a temperature register, ±1.5°C (0°C to +50°C) readable at any time through the serial interface. A dedi- ±2°C (0°C to +70°C) cated alarm output, OT, activates if the conversion result ±3°C (-40°C to +85°C) exce
