Introduction

AD8047AR-EBZ is an evaluation board from Analog Devices that is designed to help engineers and hobbyists evaluate the features and performance of high-efficiency op amps. It is a general-purpose dual operational amplifier that is widely used in a variety of applications.

Basic Usage

AD8047AR-EBZ is capable of operating as an inverting or non-inverting amplifier, providing either push-pull or single-ended output. It can also be used for differential to single-ended conversion, signal buffering, voltage summing, current limiter, and signal splitting.

Application Field

AD8047AR-EBZ can be used in a wide range of applications, such as audio applications requiring precise voltage control. It can be used in filters and sample-and-hold circuits, to ensure maximum control for sound processing. Moreover, it can be employed in power management applications that require a reliable voltage source with high switching speed.

Working Principle

AD8047AR-EBZ uses a differential amplifying principle that offers excellent noise performance. The board uses a high-gain, low-noise, complementary JFET architecture to amplify input signals. It is designed to minimize power consumption where higher speed and lower noise are paramount.The device works by integrating two identical operational amplifiers on a single MCU pin. Each of the amplifiers has its own input and output pins. These are connected to two signal pins that can be used for input conditioning and amplification. The operation amplifier uses a feedback loop to maintain a constant voltage between the two input pins. This provides excellent output signal accuracy and common-mode noise immunity.

Conclusion

AD8047AR-EBZ is a versatile and very powerful evaluation board from Analog Devices. It is designed to evaluate the features and performance of high-efficiency op amps. It is capable of operating as an inverting or non-inverting amplifier, providing either push-pull or single-ended output. It can also be used for differential to single-ended conversion, signal buffering, voltage summing, current limiter, and signal splitting. It uses a high-gain, low-noise, complementary JFET architecture to amplify input signals and offers excellent output noise performance.
