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 co sts are required. For dual supply designs without switching noise, use MAATCC0012. Functional Schematic Pin Configuration3 Pin No. Function Pin No. Function

  • Restrictions on Hazardous Substances, European Union Directive 2002/95/EC. 1. Pins 10 and 29 must be isolated. 2. V EE 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.
