Description
The MAAD-007080 is a GaAs FET 6-bit digital
attenuator with integral TTL driver. Step size is 1 dB
providing a 50 dB total attenuation range. This
device is in a PQFN plastic surface mount package.
MAAD-007080 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
MAAD-007082-000100.

1. The exposed pad centered on the package bottom must be
connected to RF and DC ground. (For PQFN Packages)
2. Pins 10 & 29 must be isolated
3. -Vee is produced internally and requires a .1µF cap to GND.
Generated noise is typical of switching DC-DC Converters.

4. During turn-on, the device requires an initial “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 can provide a minimum of 100 mA “Turn-on Current”.

6. Exceeding any one or combination of these limits may cause
permanent damage to this device.
7. MACOM does not recommend sustained operation near these
survivability limits.
8. Standard CMOS TTL interface, latch-up will occur if logic
signal is applied prior to power supply.
