Overview
The AD605ARZ-RL from Analog Devices Inc. is a low noise, accurate, dual-channel, linear-in-dB variable gain amplifier (VGA). This device is optimized for applications requiring high performance, wide bandwidth variable gain control. It operates from a single 5 V supply and features differential inputs and unipolar gain control, making it easy to use in various signal processing scenarios.
The AD605ARZ-RL is particularly suited for high-speed signal processing applications, data acquisition systems, instrumentation, communication systems, and radar systems. Its compact SOIC-16 package makes it ideal for surface-mount technology, and it operates reliably over a temperature range of -40°C to +85°C.
