Description
M/A-COM’s MAATCC0012 is a GaAs FET 4-Bit digi-
tal attenuator with integral driver. Step size is 2 dB
providing a 30 dB attenuation range. This device is
in an PQFN plastic surface mount package. The
MAATCC0012 is suited for use where accuracy, fast
speed, very low power consumption and low costs
are required.

Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
Moisture Sensitivity
The MSL rating for this part is defined as Level 2
per IPC/JEDEC J-STD-020. Parts shall be stored
and/or baked as required for MSL Level 2 parts.
