Overview
The AD602AR-REEL7, produced by Analog Devices Inc., is a dual-channel, low noise, variable gain amplifier. This component is part of the AD600/AD602 series, optimized for applications requiring precise gain control, low noise, and wide bandwidth. The AD602 specifically offers a gain range of −10 dB to +30 dB, making it suitable for various high-performance applications such as ultrasound imaging, high-performance audio, and RF AGC systems. The amplifier utilizes Analog Devices' proprietary X-AMP® architecture, which combines a variable attenuator with a high-speed fixed gain amplifier to achieve its performance objectives.
