The 11-bit resolution translates to roughly 0.125°C per LSB, adequate for most thermal management and environmental sensing tasks. ## Programmable features and power modes The DS1631S+ includes a One-Shot conversion mode for single-read operations, an output switch that can be configured as a thermostat or comparator, programmable temperature limit registers, and programmable resolution (9 to 12 bits). The Standby Mode reduces quiescent current between conversions, useful for battery-powered or low-power sensor nodes. These features allow the sensor to function as a standalone thermostat with hysteresis, or as a polled temperature monitor under firmware control. The programmable limit registers can trigger an alarm output without continuous microcontroller polling, reducing bus traffic and firmware overhead. ## Package and board integration The tube packaging suits low-volume assembly or prototyping; for reel quantities, confirm availability at RFQ. The I²C interface requires only two pull-up resistors on SDA and SCL, plus a bypass capacitor near the supply pin. No external reference or compensation components are needed, keeping the BOM count low.","metaTitle":"DS1631S+ Digital Temp Sensor, ±0.5°C, I²C, 8-SOIC","metaDescription":"DS1631S+ digital temperature sensor, ±0.5°C accuracy, 11-bit resolution, I²C output, -55°C to 125°C range, 8-SOIC package.
