Overview
The AD22103KRZ-RL, produced by Analog Devices Inc., is a monolithic temperature sensor with integrated signal conditioning. This device is designed to operate over a temperature range of 0°C to +100°C, making it suitable for various applications requiring precise temperature monitoring.
The AD22103 features a ratiometric output, meaning the output voltage is proportional to the temperature and the supply voltage. This characteristic allows the sensor to be used with the same power supply as the analog-to-digital converter (ADC), eliminating the need for a separate precision voltage reference.
