V5 Schematic with Off-Chip Components 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. .

Pins 10 and 29 must be isolated. 2. VEE is produced internally and requires a .1 F 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.
