This amplifier is suitable for a variety of test and measurement applications, such as medical instrumentation, communications, audio and video processing, seismographs, and any other application requiring a high-performance, low-noise amplifier.

Main Features

The key features of the AD847JR-REEL include wide common-mode range, extremely low distortion, wide bandwidth, and low noise performance. With an input voltage range of minus 40V to plus 40V and a maximum gain of 63 dB, the amplifier produces a very accurate output waveform with a low distortion of only 0.0005%. The amplifier also has a bandwidth of 160 MHz and a low noise floor of -110dB.

Working Principle

The AD847JR-REEL consists of two amplifiers in one package, with one being the inverting and the other being the non-inverting amplifier. The amplifiers are both AC-coupled and use single ended inputs, meaning that a single input signal is applied to the input of one of the amplifiers, and the output of the other amplifier is connected to the output of the first amplifier. This creates a cascade of two amplifiers to increase the gain and reduce the noise.The amplifier uses a two-stage architecture, with the first stage being a high gain voltage amplifier and the second stage being a high current output stage. The input stage has a high common mode range and wide bandwidth, ensuring low distortions at most gains, while the output section delivers low out of band slew-rate noise, distortion and wide bandwidth performance.

Conclusion

The AD847JR-REEL is an advanced and high-performance linear amplifier manufactured by Analog Devices Inc. It is used in a wide variety of linear applications and is an excellent choice for those seeking an amplifier with low distortion performance and wide bandwidth. With a wide common-mode range, low distortion and wide bandwidth, the amplifier is a highly reliable choice for a variety of test and measurement applications. The amplifier also has a two-stage architecture to further reduce noise and increase gain.
