Description
MACOM's MAAD-009170-000100 is a GaAs pHEMT
5-bit digital attenuator with integral TTL driver in an
PQFN plastic surface mount package. Step size is
0.5 dB providing a 15.5 dB total attenuation range.
This design has been optimized to minimize phase
variation over the attenuation range. MAAD-009170000100 is ideally suited for use where accuracy, fast
switching, very low power consumption and low
intermodulation products are required. Typical
applications include dynamic range setting in
precision receiver circuits and other gain/leveling
control circuits.

Handling Procedures
Please observe the following precautions to avoid
damage:
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.
