GENERAL DESCRIPTION

The AD8337 is a low noise, single-ended, linear-in-dB, general purpose variable gain amplifier (VGA) usable at frequencies from dc to 100 MHz; the ?3 dB bandwidth is 280 MHz. Excellent bandwidth uniformity across the entire gain range and low output-referred noise makes the AD8337 ideal for gain trim applications and for driving high speed analog-to digital converters (ADCs).
