Temperature sensors are devices that convert temperature variations into measurable electrical signals, and are used to monitor temperature and temperature changes in a wide variety of applications. The AD7417BR is one such temperature sensor, and belongs to the Analog and Digital Output category. This sensor provides temperature readings in the form of a voltage or analog current output, as well as in the form of a digital output.

The AD7417BR is a highly accurate, monolithic integrated circuit with high linearity and low noise. It uses a two-stage thermoelectric device structure to provide a very linear temperature coefficient. The Sensor also has a low offset voltage and a low temperature coefficient of the offset voltage which makes it ideal for both low temperature and high temperature applications.

The main features of the AD7417BR are its high linearity, low noise, wide operating temperature range, low offset voltage and low temperature coefficient. The AD7417BR can measure temperature from -50°C to +150°C and its accuracy is within ±1.0°C, thus making it an ideal choice for temperature sensing applications such as hot water supply, cold storage, HVAC, food service, and more.

The AD7417BR sensor is powered by a 12Vdc power supply, and has an operating current of 5mA. The sensor has an output voltage range of 0-2.5V for both the voltage and the digital outputs. The voltage output is linearly proportional to the measured temperature, while the digital output provides a binary value that is proportional to the measured temperature. The data bits from the sensor are transferred via an SPI (Serial Peripheral Interface) bus.

The AD7417BR is based on the CMOS thermoelectric device structure. This structure enables the sensor to measure temperature with high accuracy and with low power consumption. The sensing element is isolated from the electronics by a flexible silicone membrane, which provides optimal thermal isolation and helps prevent contaminants and systemic errors. The precision compensation circuit ensures accurate temperature readings, even under low temperature variations.

The AD7417BR can be used in a wide variety of temperature sensing applications, such as hot water supply, cold storage, HVAC, food service, and more. With its wide operating temperature range, linear output, low power consumption and digital interface, the AD7417BR can be used in a variety of temperature sensing applications to provide reliable, accurate temperature readings.
