AD22100SR

AD22100SR Description

The AD22100SR 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 -50°C to +150°C range with a ±2°C accuracy at room temperature (±4°C across the full range). Its 22.5mV/°C linear output slope simplifies interfacing with ADCs or microcontrollers, while its 4V to 6.5V supply range ensures compatibility with standard power rails. The sensor is EAR99 and HTSUS 8542.39.0001 compliant, making it suitable for global export.

AD22100SR Features

• Analog Voltage Output: Linear 22.5mV/°C response for direct ADC integration.
• Wide Operating Range: -50°C to +150°C, ideal for harsh environments.
• High Accuracy: ±2°C at 25°C (±4°C max error).
• Low Power Consumption: Operates from 4V to 6.5V, minimizing system power overhead.
• Surface-Mount Design: 8-SOIC package (MSL 1) for compact PCB integration.
• Obsolete Status: Still reliable for legacy designs but consider newer alternatives for future projects.

AD22100SR Applications

• Industrial Control: Motor/transformer temperature monitoring.
• Automotive Systems: Cabin climate control, battery thermal management.
• Consumer Electronics: Overheat protection in power supplies.
• Medical Devices: Precision thermal sensing in portable equipment.
• HVAC Systems: Airflow and ambient temperature regulation.

Conclusion of AD22100SR

The AD22100SR excels in analog temperature sensing with its linear output, wide range, and robust accuracy, though its obsolete status may limit new designs. Its ease of integration and industrial-grade reliability make it a strong choice for legacy systems requiring stable performance. For modern applications, evaluate newer Analog Devices alternatives with enhanced features like digital interfaces or lower power consumption.
