Overview
The AD600JRZ-R7, produced by Analog Devices Inc., is a dual-channel, low noise, variable gain amplifier. This component is part of the AD600 series, which is optimized for use in various high-performance applications, particularly in ultrasound imaging systems. Each channel of the AD600 comprises a variable attenuator followed by a high-speed fixed gain amplifier, allowing for precise gain control and minimal distortion. The gain-control interfaces are fully differential, providing a high input resistance and a linear control function in dB.
