Working Principle

The ADA4891-1ARJZ-R7 consists of two Op-Amps, connected in parallel. Each Op-Amp is made up of three stages that are connected in series, wherein the first stage amplifies input signals, the second stage amplifies again and the third stage controls two transistors, which form a current-to-voltage converter. Input signals from the current-to-voltage converter is then fed to the first op-amp for further amplification. The output of this op-amp is also fed to the second op-amp and filtered, producing an output signal. This output signal is then converted back to current and transmitted to the output terminals.

The ADA4891-1ARJZ-R7 is capable of delivering high performance, with its excellent linearity, low noise, and high precision. Its high power efficiency also makes it an ideal fit for discrete applications, as well as commercial device designs. Furthermore, its low-power operation makes it feasible in low-power environments.
