GENERAL DESCRIPTION

The AD8331/AD8332/AD8334 are single-, dual-, and quad channel ultralow noise, linear-in-dB, variable gain amplifiers (VGAs). Optimized for ultrasound systems, they are usable as a low noise variable gain element at frequencies up to 120 MHz. Included in each channel are an ultralow noise preamplifier (LNA), an X-AMPÂ® VGA with 48 dB of gain range, and a selectable gain postamplifier with adjustable output limiting.
The LNA gain is 19 dB with a single-ended input and differential outputs. Using a single resistor, the LNA input impedance can be adjusted to match a signal source without compromising noise performance.
