Description
The MAAD-009194-000100 is a GaAs FET 5-bit
digital attenuator with a 1 dB minimum step size and
31 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-009194-000100 is ideally suited for use
where accuracy, fast switching, very low power
consumption and low intermodulation products are

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.
