Description
M/A-COM’s MAAD-007077-000100 is a GaAs FET 4-Bit digital attenuator with integral driver. Step size is 1 dB providing a 15 dB attenuation range. This device is in an PQFN plastic surface mount pack- age. The MAAD-007077-000100 is suited for single supply applications where accuracy, fast speed, low power consumption and low co sts are required. For dual supply designs without switching noise, use MAADCC0006.

- Restrictions on Hazardous Substances, European Union Directive 2002/95/EC. 1. Pins 10 & 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)

During turn-on, the device requires an initial start up current (Icc) specified as “Turn-on Current”. Once operational, Icc will drop to the specified levels. 5. The DC-DC converter is guaranteed to start in 100 µs as long as the power supplies have the maximum turn-on current available for start- up.
