The DS1631S+T&R is a temperature sensor with a thermistor element inside that provides an analog or digital output. This device is used extensively in consumer, automotive, industrial, and medical applications, and is capable of measuring temperatures from -50°C to +150°C. It offers high accuracy with a maximum error of ±1°C. The ±1°C accuracy is achieved over the wide temperature range of -50°C to +150°C, and it has a resolution of 0.0625°C, making it ideal for precision applications.

The thermistor element inside the DS1631S+T&R is a two-terminal device with a variable resistance that is proportional to the temperature of the element. The resistance changes in a predictable manner when exposed to a temperature change. The DS1631S+T&R has two functions: a temperature sensing element that provides an analog or digital output, and a heater output that is used to maintain the temperature of the thermistor in a stable range. The thermistor element consists of a single element and two contacts. The two contacts are connected to a pair of pins on the DS1631S+T&R. The output pins are connected to the thermistor element through a resistor ladder network, which converts the thermistor signal to either an analog or digital output.

The DS1631S+T&R measures temperature by sensing the resistance of the thermistor element. As the resistance of the thermistor changes, the voltage across the terminals of the thermistor changes, and this change is measured by the DS1631S+T&R as a temperature value. The DS1631S+T&R can provide both analog and digital outputs. The analog output is a voltage that is proportional to the temperature of the thermistor. The digital output is a binary code that is proportional to the temperature of the thermistor.

The heater output of the DS1631S+T&R can be used to maintain the temperature of the thermistor in a fixed temperature range. The heater output is controlled by the temperature set point, which is the temperature at which the heater output is turned on. The heater output can be adjusted to the desired temperature range by changing the voltage applied to the heater output.

The DS1631S+T&R is an ideal solution for applications that require high accuracy, precise temperature measurements, and stability over a wide temperature range. It is an affordable and reliable solution for consumer, automotive, industrial, and medical applications. The device is easy to integrate into systems, and offers a highly accurate temperature measurement capability with a maximum error of ±1°C. The thermistor element can be replaced if it fails, and the heater can be turned on or off to maintain the desired temperature range.
