MD3880 Overview
The MD3880 is a 4-channel, variable gain amplifier (VGA) paired with a low noise amplifier (LNA) that delivers fully differential input and output for ultrasound applications. The 18.5dB gain of the LNA allows the whole channel to have 0.74nV/√Hz of input-referred voltage noise at 5MHz. The LNA is capable of active impedance control to improve noise performance, provided that the applications can take advantage of...
