Overview
The AD22100SR, produced by Analog Devices Inc., is a monolithic temperature sensor with on-chip signal conditioning. This device is designed to operate over a wide temperature range of -50°C to +150°C, making it highly suitable for various industrial, HVAC, instrumentation, and automotive applications. The AD22100SR features a ratiometric output, meaning its output voltage is proportional to the temperature times the supply voltage, which simplifies system design and reduces overall system cost when interfacing with analog-to-digital converters (ADCs).
