Description
M/A-COM's MAAD-008790-000100 is a GaAs
pHEMT 5-bit digital attenuator with integral TTL
driver. This attenuator was designed to minimize
phase variation over attenuation. Step size is 1.0 dB
providing a 31.0 dB total attenuation range. This
device is in an PQFN plastic surface mount
package. MAAD-008790-000100 is ideally suited for
use where accuracy, constant phase over attenuation, very low power consumption and low costs are
required.

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.
