Description

The MAAD-007080 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 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.
