NAME
DESCRIPTION
1, 4
VCC
Supply Voltage. Bypass with capacitors as specified in the typical application circuits. Place capacitors
as close to the pin as possible (see the Power-Supply Connections section).
2, 3
INHI, INLO Differential RF Inputs
5
PWDN
Power-Down Input. Drive PWDN with a logic-high to power down the IC. PWDN must be connected to
GND for VS between 4.75V and 5.25V with R4 = 75Ω.
6
GND Ground. Connect to the printed circuit (PC) board ground plane.
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).

EP
Exposed Pad (TDFN Package Only). Connect EP to GND using multiple vias, or the EP can also be left
unconnected.
