Overview
The AD600ARZ-R7, produced by Analog Devices Inc., is a dual-channel, low noise, wideband variable gain amplifier. This component is part of the X-AMP® series, designed to provide precise gain control, low noise, and wide bandwidth, making it suitable for various applications, including ultrasound imaging systems and other fields requiring high precision and low distortion.
The AD600ARZ-R7 features a proprietary circuit design that includes a variable attenuator followed by a high-speed fixed gain amplifier. This architecture ensures that the amplifier does not have to handle large input signals, allowing for precise gain definition and dynamics through the use of negative feedback.
