Working Principle

The ADUM3190BRQZ is a high precision, differential amplifier that operates using a differential input stage and a common mode output stage. The differential input allows the amplifier to operate as a differential amplifier or a common mode amplifier. As a differential amplifier, the device converts the differential input into a single-ended output, while as a common mode amplifier, the device amplifies the difference between the two input signals. The amplifier compensates for common mode offsets and rejects common mode voltages, thus providing accurate and precise results.

The amplifier features a precision auto-null circuit, which automatically cancels out offset voltages. This helps to reduce the errors caused by the offsets, resulting in more accurate and precise results. In addition, the amplifier includes a power supply rejection ratio (PSRR) of typically 60dB, which means that the amplifier is not easily affected by any fluctuations in the power supply. The power supply rejection ratio is an important feature of the amplifier, as it ensures that a steady voltage is maintained even when the power supply fluctuates.

The ADUM3190BRQZ also features a wide gain range, allowing it to be used for both low level signals and high level signals. The amplifier is also capable of providing both high-speed and low-speed output signals, making it suitable for use in both audio and instrumentation applications. In addition, the amplifier has a wide bandwidth, allowing it to be used for applications that require precise measurement of high-frequency signals.
