Description
The MAAD-007078 is a GaAs FET 5-bit digital
attenuator with integral TTL driver. Step size is
1.0 dB providing 31 dB total attenuation range. This
device is in an FQFP-N plastic surface mount
package. The MAAD-007078 is ideally suited for use
where accuracy, fast speed, very low power
consumption and low costs are required.
For dual supply designs without DC-DC converter
noise, use MAATCC0010.

1. Pins 10 & 29 must be isolated
2. The negative voltage Vee is produced internally and
requires a 0.1µF 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)
