Description
M/A-COM's MAAD-007080-000100 is a GaAs FET
6-bit digital attenuator with integral TTL driver. Step
size is 1 dB providing a 50 dB total attenuation
range. This device is in a PQFN plastic surface
mount package. MAAD-007080-000100 is ideally
suited for use where accuracy, fast speed, very low
power consumption and low costs are required. For
dual supply designs without switching noise, use
MAAD-007082-000100.

The exposed pad centered on the package bottom must be
connected to RF and DC ground. (For PQFN Packages)
Pins 10 & 29 must be isolated
-Vee is produced internally and requires a .1µF cap to GND.
Generated noise is typical of switching DC-DC Converters.

4. During turn-on, the device requires an initial “Turn-on Current”.
Once operational, Icc will drop to the specified levels.
5. The DC-DC converter is guaranteed to start in 100 µs as long as
the power supplies can provide a minimum of 100 mA “Turn-on
Current”.
