In linux kernel since version 3.1 (release Date: 2011-10-24)  
Say yes here to build support for Analog Devices AD8366 and similar
gain amplifiers. This driver supports the following gain amplifiers
from Analog Devices:
AD8366 Dual-Digital Variable Gain Amplifier (VGA)
ADA4961 BiCMOS RF Digital Gain Amplifier (DGA)
ADL5240 Digitally controlled variable gain amplifier (VGA)
HMC792A 0.25 dB LSB GaAs MMIC 6-Bit Digital Attenuator
HMC1119 0.25 dB LSB, 7-Bit, Silicon Digital Attenuator

To compile this driver as a module, choose M here: the
module will be called ad8366.
