MD3880 - 4-Channel Low-Noise Amplifier

General Description

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.

Key Features

  • 2.5V ± 0.125V operation 4 independent channels Fully differential inputs and outputs 0.74nV/√Hz input-referred noise at 18.5dB gain Ultra low current noise 0.35pA /√Hz 600kΩ /17.5pF internal input impedance 100MHz amplifier bandwidth Linear-in-dB continuous variable gain control Four digital programmable gain settings for PGA 60MHz whole channel bandwidth at maximum gain 70dB maximum channel gain Variable gain scaling c.
