EP
Power-Down Input. Drive PWDN with a logic-high to power down the IC. PWDN must be connected to
GND for V S between 4.75V and 5.25V with R4 = 75 Ω .
Ground. Connect to the printed circuit (PC) board 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 Pad (TDFN Package Only). Connect EP to GND using multiple vias, or the EP can also be left
unconnected.
