MD3880 Datasheet (Supertex) - 4-Channel Low-Noise Amplifier

MD3880, 4-Channel Low-Noise Amplifier

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 cap
