Description
M/A-COM's MAATCC0011 is a GaAs FET 6-bit
digital attenuator with integral TTL driver. Step size
is 0.5 dB providing a 31.5 dB total attenuation range.
This device is in an PQFN plastic surface mount
package. The MAATCC0011 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
MAATCC0009.

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)
