Description
M/A-COM's MAAD-007080-000100 is a GaAs FET
6-bit digital attenuator with integral TTL driver. Step
size is 1 dB providing a 50 dB total attenuation
range. This device is in a PQFN plastic surface
mount package. MAAD-007080-000100 is ideally
suited for use where accuracy, fast speed, very low
power consumption and low costs are required. For
dual supply designs without switching noise, use
MAAD-007082-000100.

1. The exposed pad centered on the package bottom must be
connected to RF and DC ground. (For PQFN Packages)
2. Pins 10 & 29 must be isolated
3. -Vee is produced internally and requires a .1µF cap to GND.
Generated noise is typical of switching DC-DC Converters.

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.
