GENERAL DESCRIPTION

The AD8335 is a quad variable gain amplifier (VGA) with low noise preamplifier intended for cost and power sensitive applications. Each channel features a gain range 48 dB, fully differential signal paths, active input preamplifier matching, and user-selectable maximum gains of 46 dB and 38 dB. Individual gain controls are provided for each channel.

FEATURES

Low noise preamplifier (PrA)

Voltage noise = 1.3 nV/√Hz typical

Current noise = 2.4 pA/√Hz typical

NF = 7 dB (RS = RIN = 50 ?)

Single-ended input; VIN max = 625 mV p-p

Active input match

Input SNR (noise bandwidth = 20 MHz) = 92 dB

VGA

Differential output

VOUT max = 5 V p-p, RL = 500 ? differential
