Description
M/A-COM's AT65-0263 is a GaAs FET 5-bit digital
attenuator with integral TTL driver. Step size is 1.0
dB providing 31 dB total attenuation range. This
device is in a SOW-16 plastic surface mount
package. The AT65-0263 is ideally suited for use
where accuracy, fast speed, very low power
consumption and low costs are required.

Handling Procedures
Truth Table (Digital Attenuator)
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.
