Working Principle
The AD8221BR is a differential input-to-output amplifier with a high CMRR. The input differential amplification stage is designed to provide a wide dynamic input range and excellent linearity with a high CMRR. The output stage provides the necessary signal conditioning to optimize the performance of the entire amplifier.
The input differential stage is designed to provide a wide dynamic input range and high linearity. The DC precision and low-noise performance of the amplifier is optimized by taking advantage of the high input impedance of the CMOS transistors. The high input impedance provides a high input signal to noise ratio with minimal loading effects.
The output stage of the AD8221BR uses the same techniques as the input stage to minimize loading effects and minimize distortion. The output stage is optimized for low-noise and low distortion, and has additional features such as output current limiting for improved safety in the event of overload.
The AD8221BR is a precision instrumentation amplifier and is ideally suited for transducer amplifiers, medical equipments, and precision instrumentation. This amplifier offers excellent linearity with a wide dynamic input range and low-noise performance. The amplifier is also well suited for biomedical instrumentation, industrial process control equipment, and data acquisition systems.
