Description
M/A-COM's MAAD-008789-000100 is a GaAs FET
2-bit digital attenuator with two 16 dB steps and 32
dB total attenuation with integral TTL driver. This
device is in a RoHS compliant PQFN plastic surface
mount package. MAAD-008789-000100 is ideally
suited for use where accuracy, 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. Environmental screening is
available. Contact the factory for information.
