Temperature sensors are an important component in many industrial processes. The DS1626S+ is a digital temperature sensor with analog outputs specifically designed for use in industrial, automotive, and consumer applications. The device measures an analog temperature signal from a thermistor or resistance temperature detector (RTD) and converts it to a digital output over an I2C-compatible communication scheme.

The DS1626S+ has several on-chip features designed to simplify the sensor design, improve performance, and control costs. First, the DS1626S+ can be configured in either a classical two-resistor voltage divider or in a three-resistor bridge configuration. This allows the user to select the optimal type of connection for their application based on cost or performance considerations. Second, the on-chip temperature conversion is simplified using an integrated programmable temperature conversion algorithm, eliminating the need for complex, processor-intensive calculations. Third, the device eliminates the need for a separate calibration table lookup by allowing the user to program an accurate temperature curve into the device. Lastly, the DS1626S+ is capable of high precision, with digital-analog conversions up to 7-bit resolution for both thermistors and RTDs.

The main application field of the DS1626S+ is automotive, industrial, and consumer applications. It can be used for various temperature-sensitive processes such as HVAC, appliances, data centers, automobiles, and medical equipment. In automotive applications, the DS1626S+ can be used to monitor engine temperature, fuel temperature, and transmission temperature. In a consumer application, the DS1626S+ can provide precise temperature measurements for use in home security and home automation systems.

The DS1626S+ operates using a simple principle of analog-to-digital conversion. The device accepts an analog temperature signal from the sensor and converts it to a digital signal using an I2C compatible communication scheme. The analog signals are amplified, filtered, and converted by the on-chip amplifier and multiplexer circuit. The device can be configured in either a two-resistor voltage divider or a three-resistor bridge configuration. For thermistor measurements, the programmable temperature conversion algorithm is used. For RTD measurements, an accurate temperature curve can be programmed into the device. The output of the device is a 16-bit digital signal, which can be read via the I2C interface.

The DS1626S+ is an ideal solution for a wide range of temperature-sensitive applications, due to its high accuracy, programmable temperature curve, and small package size. Its on-chip features allow for a simpler and cheaper design, improving performance and reducing costs. The device’s programmable temperature curve also allows for accurate temperature measurements in a variety of conditions. The DS1626S+ provides an accurate, cost-effective solution for temperature measurement in automotive, industrial, and consumer applications.
