Working Principle

The AD22103KRZ is a digital temperature sensor with a resistance temperature detector (RTD) as its sensing element. The sensing element consists of an RTD bridge circuit and an amplifier circuit that converts the resistance value of the RTD to a voltage output. This voltage output is then converted to an digital output using a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC). The ADC operates at a maximum input frequency of 200 kHz to ensure fast and reliable temperature readings. The AD22103KRZ can be configured for a variety of analog and digital outputs, including but not limited to voltage, pulse width modulation (PWM), pulse frequency modulation (PFM), and 4-20mA loop.

The AD22103KRZ has a wide temperature sensing range of -50°C to +450°C and can be used in both 1-point and 2-point temperature-sensing applications. It is also designed for extended temperature range and low-power applications, providing reliable temperature measurement in difficult conditions. It is available in a variety of form factors, including TO-220, DPAK, and SOIC, allowing for easy integration into existing systems. Each model features a high accuracy of ±0.5°C, enabling precise temperature measurements.
