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.

1.

The exposed pad centered on the package bottom must be

connected to RF and DC ground. (For PQFN Packages)

2.

Pins 10 & 29 must be isolated

3.

-Vee is produced internally and requires a .1µF cap to GND.

Generated noise is typical of switching DC-DC Converters.
