DESCRIPTION
1, 4
V
CC
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).

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 V
S
between 4.75V and 5.25V with R4 = 75
Ω
.
Ground. Connect to the printed circuit (PC) board ground plane.
6
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).

EP
Exposed Paddle. Connect EP to GND using multiple vias, or the EP can also be left unconnected.
