Description

M/A-COM’s MAAD-009195-000100 is a GaAs FET

5-bit digital attenuator with a 0.5 dB minimum step

size and 15.5 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-009195-

000100 is ideally suited for use where accuracy, fast

switching, very low power consumption and low in-

termodulation products are required. Typical appli-

cations include dynamic range setting in precision

receiver circuits and other gain/leveling control cir-

cuits. Environmental screening is available. Contact

the factory for information.

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.
