AD22100AT

AD22100AT is a monolithic temperature sensor with an on-chip signal conditioning. It can be operated over the temperature range of -50°C to +150°C, making it ideal for use in numerous HVAC, instrumentation, and automotive applications. The signal conditioning eliminates the need for any trimming, buffering, or linearization circuitry, greatly simplifying the system design and reducing the overall system cost. Due to its ratiometric nature, this device offers a cost-effective solution when interfacing with an analogue-to-digital converter. It is used in applications such as HVAC systems, system temperature compensation, board-level temperature sensing, and electronic thermostats.
