PIN FUNCTIONS
EN (Pin 1): Enable. When the input voltage is higher than
0.9V, the circuit is completely turned on. When the input
voltage is less than 0.6V, the circuit is turned off.
GND (Pins 2, 5): Ground.
VOUT (Pin 3): RF Detector Output.
VCC (Pin 4): Power Supply. This pin should be decoupled
using 100pF and 0.1µF capacitors.
RF (Pin 6): RF Input. This pin is internally biased to
VCC – 0.18V. A coupling capacitor must be used to connect
to the RF signal source.
