ENB/APC Function
The ENB/APC lead is used to turn the device on and to control the output power. If the voltage on this lead is
below VILMAX, the device is in a low-current mode. Between VIHMIN and about VCC, the device draws full supply
current and is in a power-control mode. In this region, the output power will vary with the voltage on the
ENB/APC lead as shown in Figure 5.
