Product Summary

The AD604ARZ-RL is an ultralow noise, very accurate, dual-channel, linear-in-dB variable gain amplifier (VGA) optimized for time-based variable gain control in ultrasound applications; however, the AD604ARZ-RL supports any application requiring low noise, wide bandwidth, variable gain control. Each channel of the AD604ARZ-RL provides a 300 kΩ input resistance and unipolar gain control for ease of use. User-determined gain ranges, gain scaling (dB/V), and dc level shifting of output further optimize performance. The applications of the AD604ARZ-RL include Ultrasound and sonar time-gain controls, High performance AGC systems and Signal measurement.
