CC
Supply Voltage. Bypass with capacitors as specified in the application drawing. Place capacitors as
close to the pin as possible (see
Power-Supply Connections
section).

PWDN
Power-Down Input. Drive PWDN with a logic high to power down the IC. PWDN must be connected to
GND for V

between 4.75V and 5.25V with R4 = 75
Ground. Connect to the printed circuit (PC) board ground plane.

GND
7
SET
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.
8
OUT
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).
