AD797AR-REEL

Introduction

AD797AR-REEL is an instrumentation amplifier from ADI. It is a high common-mode dynamic range of up to 65dB with excellent dc accuracy of 0.01% accuracy on gains over 35dB. This linear amplifier offers excellent common-mode rejection and high gain accuracy with very low offset and noise. It is available in industry standard dual in-line packages and pin-compatible single and quad packages.

Application Field

AD797AR-REEL can be used in many different applications such as process control, medical imaging, industrial automation and scientific research. Its excellent common-mode rejection and high gain accuracy makes it an ideal choice for use in precision signal measurement, such as remote sensing, medical monitoring, and industrial process control. Its excellent dc accuracy makes it suitable for use in low noise applications such as ultrasound, ultra-high frequency communication, and other analogue applications.

Working Principle

AD797AR-REEL is a feedback topology amplifier with two differential inputs, two feedback paths and two outputs. The differential inputs are the two inputs to the amplifier and the feedback paths are the two negative feedbacks applied to the inputs of the amplifier. The feedback network consists of a resistance network, one for each input. The resistance network applies a voltage to the sum of the two inputs, which reduces the output voltage at the second input and increases the output voltage at the first input. This allows the amplifier to have a high common-mode rejection and very low offset and noise.

Conclusion

In conclusion, AD797AR-REEL is a high common-mode dynamic range of up to 65dB linear amplifier with excellent dc accuracy and low offset and noise. It is available in industry standard dual in-line packages and pin-compatible single and quad packages. Its excellent common-mode rejection and high gain accuracy makes it an ideal choice for use in precision signal measurement, such as remote sensing, medical monitoring, and industrial process control.
