Evaluation and demonstration boards and kits are designed to make it easy for electrical engineers, roboticists, automation professionals, and the like to test and demonstrate a variety of types of circuitry and systems. One such board is the EVAL-ADM2486EBZ, a high performance, low cost differential voltage receiver board. This board is used to quickly and accurately measure differential voltage in both in-circuit and off-circuit testing scenarios. In this article, we will review the application of the EVAL-ADM2486EBZ and its working principle.

Application

The EVAL-ADM2486EBZ is a differential voltage receiver board designed for in-circuit measurements on high pertance circuits such as those found in robotics, industrial automation, and other robotic applications. The board is designed to measure differential voltage in three different voltage ranges; ±15V, ±5V, and ±25V. It can measure the relative voltage between two inputs with a resolution of 1mV and an accuracy of 1µV. The board also features differential inputs with ESD protection. This allows for accurate, safe measurements while providing EMI immunity and electrostatic protection.

In addition to its use in in-circuit measurements, the board can also be used for off-circuit measurements. It features a fully internalized, built-in differential voltage amplifier that can measure differential voltage between two external devices without an external voltage source. This is particularly useful in testing and analyzing off-circuit systems, such as those used in automated manufacturing processes. The EVAL-ADM2486EBZ can also be used for signal tracing, as it has a built-in DC-coupled differential amplifier that can trace signals up to 5MHz.

Working Principle

The EVAL-ADM2486EBZ differential voltage receiver board utilizes a differential amplifier to measure the voltage differential between two inputs. This differential voltage is applied to the input of the differential amplifier, which amplifies the voltage differential using an external power supply. The amplified voltage is then output from the differential amplifier to the board’s output terminals, where it can be measured with an external voltmeter.

The board’s differential amplifier uses a differential design to minimize the effect of changes in the surrounding environment, such as RF noise, on the output. It also uses a low-gain negative feedback system to reduce the gain of the amplifier, further providing immunity from noise. The amplifier’s output also includes an ESD protection feature, which provides immunity from electrostatic discharge.

The EVAL-ADM2486EBZ also uses an internal amplifier to amplify the differential voltage from the external sources. This amplifier is a wideband AC amplifier, and is used to amplify input signals up to 5MHz. It also features a unity-gain common-mode feedback circuit, which helps reduce the effect of both common-mode and normal-mode noise on the output of the board. The board also provides an 80dB common-mode rejection ratio between the differential and single-ended output.

The EVAL-ADM2486EBZ also features an integrated low-pass filter to reduce the effect of high-frequency noise on the output. The low-pass filter allows the board to achieve its excellent signal-to-noise ratio. The board also includes a digital-to-analog converter, which can convert the output of the differential voltage receiver into a digital signal. This digital signal can then be tested with signal-analysis programs to analyze the differential voltage.

Conclusion

In conclusion, the EVAL-ADM2486EBZ differential voltage receiver board is an excellent tool for measuring differential voltage in both in-circuit and off-circuit scenarios. It is designed for use in robotics, industrial automation, and other robotic applications, and offers excellent signal quality and wideband AC performance. It also provides excellent ESD protection, low-pass filtering, and integrated digital-to-analog conversion. With its wide range of features and excellent performance, the EVAL-ADM2486EBZ is an ideal solution for measuring differential voltage.
