Description  
M/A-COM‘s MAAD-007079-000100 is a GaAs FET  
4-Bit digital attenuator with integral driver. Step size  
is 2 dB providing a 30 dB attenuation range. This  
device is in an FQFP-N plastic surface mount pack-  
age. The MAAD-007079-000100 is suited for single  
supply applications where accuracy, fast speed, low  
power consumption and low costs are required. For  
dual supply designs without switching noise, use  
MAATCC0012.

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