Pad Description
FUNCTION
Positive Supply Voltage of Input Stage. Apply +3.3V if VCCD = +3.3V. If VCCD > +3.47V, disconnect from sup-
ply and decouple to GND.
External Filter Capacitor. A capacitor connected between CHF+ and CHF- is used for setting the low-frequency
cutoff.

Signal Input
No Connect
The voltage at this node programs the gain of the power detector. Connect a resistor between PDC and INV to
adjust the LOP threshold.

Filter Node for Power Detector. A capacitor connected between CPD+ and CPD- will provide additional filtering
to the rectifier output within the power detector.
