AD22100AR

AD22100AR Description

The AD22100AR from Analog Devices Inc. is an analog voltage output temperature sensor designed for precision temperature measurement in industrial, automotive, and consumer applications. Housed in an 8-SOIC surface-mount package, it operates over a -40°C to +85°C range with a supply voltage of 4V to 6.5V. The sensor delivers a linear output of 22.5mV/°C, ensuring high-resolution temperature monitoring. With an accuracy of ±2°C (best case) and ±3.7°C (worst case), it provides reliable performance across its full operating range. The device is classified under EAR99 and HTSUS 8542.39.0001, making it suitable for global export.
