6-bit digital attenuator with a 1 dB minimum step size
and a 50 dB total attenuation range. This device is in
a SOW-24, wide body plastic surface mount
package. The MAAD-007086-000100 is ideally
suited for use where accuracy, fast speed, 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.
2
2. Exceeding any one or combination of these limits may cause
permanent damage to this device.
3. MACOM does not recommend sustained operation near these
survivability limits.
4. Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
