RF Input.
Connect pin to VS for normal operation.
Connect pin to ground for disable mode.
Setpoint input for operation in controller
mode. To operate in detector mode connect
VSET to V_UP
Connection for an external capacitor to slow
the response of the output. Capacitor is con-
nected between FLTR and V_UP.

*Stresses above those listed under Absolute Maximum Ratings may cause permanent
damage to the device. This is a stress rating only; functional operation of the device
at these or any other conditions above those indicated in the operational section
of this specification is not implied. Exposure to absolute maximum rating conditions
for extended periods may affect device reliability.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD8314 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
