Use this VCC to connect to VCTL signal with
a shorting link
Connect to 3.3 V (VCC) for maximum gain
and power output. For power control
connect to a variable voltage source between
0 V and 3.3 V.
Provided as a ground connection for the
VCTL signal.
Use this VCC to connect to VRAMP signal
with a shorting link
0 V – 1.5 V applied = Device Disabled
2 V – VCC applied = Device Enabled
Provided as a ground connection for the
VRAMP signal
