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.

During turn-on, the device requires an initial “Turn-on Current”.
Once operational, Icc will drop to the specified levels.
The DC-DC converter is guaranteed to start in 100 µs as long as
the power supplies can provide a minimum of 100 mA “Turn-on
Current”.
