Working Principle of ADA4004-1ARZ-R7

The core of the ADA4004-1ARZ-R7 is a differential amplifier which consists of two independent amplification units. Each of these units consists of two input transistors, one differential pair and an output stage, thus forming an additional amplification. Both stages are operating at the same frequency and thus the input voltage is amplified by both stages. The output stage amplifies the input voltage and the output voltage is available at the amplifier output.

The main function of the ADA4004-1ARZ-R7 is to amplify a differential input voltage into a single-ended output voltage. This single-ended output voltage can then be amplified further, if necessary. The ADA4004-1ARZ-R7 operates over a wide range of common-mode and/or differential-mode gain and input Offset voltages. Additionally, the ADA4004-1ARZ-R7 also offers a low input bias and output saturation current, low distortion and noise, and low power consumption.
