The AA101-80 is a 5-bit, single positive control GaAs IC FET
digital attenuator in a low-cost SSOP-16 package. This attenuator
has an LSB of 1 dB and a total attenuation of 31 dB. The
attenuator requires external DC blocking capacitors, positive
supply voltage (VS) and five individual bit control voltages (V1–V5).
The AA101-80 is particularly suited where high attenuation
accuracy, low insertion loss and low intermodulation products
are required. Typical applications include base station, wireless
data, and wireless local loop gain level control circuits.

Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION: Although this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all times
from ESD. Static charges may easily produce potentials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
