Application Information
The MAAL-011129 is designed to be easy to use yet
provide high performance. The ultra small size, no
matching, and simple bias application allows easy
placement on system boards.
Single-Supply Operation
With a single supply and pin 4 (V_BIAS) left open the
amplifier will default to power down mode.
Connecting V_DD to V_BIAS using an external resistor R_B
enables single-supply operation of the amplifier, and
the value of external resistor R_B sets the desired
current I_DD. The following table shows drain current
(I_DD) versus external resistor (R_B) values for V_DD
voltages of 5 V and 3.3 V:
V_DD = 3.3 V

Grounding
It is recommended that the total ground (common
mode) inductance not exceed 0.03 nH (30 pH). This
is equivalent to at least four 8 mil (200 µ) vias per
8 mil board (200 µ) be place under the device to
ground.
