Product Summary

The AD602ARZ is a dual channel, low noise, variable gain amplifier optimized for use in ultrasound imaging systems. The lower gain of the AD602ARZ results in an improved signal-to-noise ratio (SNR) at the output. However, both products have the same 1.4 nV/√Hz input noise spectral density. The decibel gain is directly proportional to the control voltage, accurately calibrated, and supply and temperature stable. The applications of the AD602ARZ include Ultrasound and sonar time-gain controls, High performance audio and RF AGC systems and Signal measurement.
