Description
The MAADSS0013 is a 4-bit, 1-dB step GaAs MMIC
digital attenuator in a lead-free 3mm PQFN-16LD
surface mount plastic package. The MAADSS0013
is ideally suited for use where high accuracy, very
low power consumption and low intermodulation
products are required. Typical applications include
radio, cellular, wireless LANs, GPS equipment and
other gain / level control circuits.
The MAADSS0013 is part of a digital attenuator
family. This family includes 4, 5, and 6 bit
attenuators with 0.5, 1, or 2 dB steps and up to 31.5
range.

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.
