Description
MACOM’s MAATCC0006 is a GaAs FET 4-bit digital
attenuator with a 2.0 dB minimum step size and a
30 dB total attenuation range. This device is in a
SOIC-16 plastic surface mount package. The
MAATCC0006 is ideally suited for use where
accuracy, fast speed, very low power consumption
and low costs are required. Typical applications
include dynamic range setting in precision receiver
circuits and other gain/leveling control circuits.
