Description
MACOM’s MAAD-009195-000100 is a GaAs FET
5-bit digital attenuator with a 0.5 dB minimum step
size and 15.5 dB total attenuation. The design has
been optimized to minimize phase variation over the
attenuation range. This attenuator and integral TTL
driver is in a hermetically sealed ceramic 16-lead
surface mount package. The MAAD-009195-000100
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. Environmental screening is
available. Contact the factory for information.

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.
