OUT
Supply Voltage. Bypass with capacitors as specified in the application drawing. Place capacitors as
close to the pin as possible (see the Power-Supply Connections section).
Power-Down Input. Drive PWDN with a logic-high to power down the IC. PWDN must be connected to
GND for V
Ground. Connect to the PCB ground plane.
Set-Point Input. To operate in detector mode, connect SET to OUT. To operate in controller mode,
connect a precision voltage source to control the power level of a power amplifier.
Detector Output. In detector mode, this output provides a voltage proportional to the log of the input
power. In controller mode, this output is connected to a power-control input on a power amplifier (PA).
Exposed Paddle (TDFN package only). Connect EP to GND using multiple vias, or the EP can also be left
unconnected.
