ADA4817-1ARD-EBZ

The ADA4817-1ARD-EBZ evaluation board is a versatile piece of equipment from Analog Devices, Inc. It is based on the ADA4817 high performance current feedback amplifier, and is intended to provide an evaluation platform for the ADA4817 which enables evaluators to get a feel for the performance of the amplifier in terms of its output characteristics, input characteristics, and overall performance.

The ADA4817-1ARD-EBZ is classified as an evaluation board in the category of operational amplifiers. These boards serve as a means to evaluate the power and accuracy of an operational amplifier before it is released to be used in a larger circuit. This helps engineers to detect any discrepancies that may have been caused during manufacture, or alternatively highlight any design flaws that may have been overlooked.

The ADA4817-1ARD-EBZ employs the ADA4817, which is a high-speed, high-voltage, low-input bias current, and low-noise current feedback amplifier. The amplifier consists of two stages, an input stage, and an output stage. The input stage, a high-performance point-of-load amplifier, features a programmable gain of 1, 2, 4, and 8 (with corresponding corner frequencies of 66 kHz, 22 kHz, 5.5 kHz, and 1.4 kHz respectively). The output stage is composed of a pair of complementary Darlington-connected transistors for power buffering.

The ADA4817-1ARD-EBZ provides users with a wide range of features that can be employed for different applications. Of these features, gain setting allows the user to tailor the output signal with one of the four gains available. The board also includes an enable filter and gain shifting capabilities, along with a slew rate and bandwidth of 200 volts per microsecond and 1.4 megahertz respectively.

The board also provides users with various functions for setting up their device. These include a digital potentiometer for controlling the gain of the amplifier, a 0v to 5v input chip adc and a factory preset reference gain setting. Furthermore, the board also supports external current gain and slew rate control through the use of an external current measurement circuit.

The ADA4817-1ARD-EBZ is an extremely versatile evaluation board that can be used in a wide range of applications. It is especially useful for applications requiring high-speed, high-voltage, low-input bias current, and low-noise performance. The configuration of the board enables direct comparison of multiple gains, including 1, 2, 4, and 8. It can also be used to measure the effect of a current feedback amplifier on the signal waveform, and to compare results to the desired waveform without needing to make any changes to the board. Lastly, the enable filter and gain shifting allows users to monitor and adjust the amplifier’s output as required.
