NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent 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.

Function
Device Common. Connect to low impedance ground.
High Input Impedance to Channel A. Must be ac-coupled.
A capacitor to ground at this pin sets the offset compensation filter corner
and provides input decoupling.
Voltage Supply (VS), 2.7 V to 5.5 V.
A capacitor to ground at this pin sets the offset compensation filter corner
and provides input decoupling.
Input to Channel B. Same structure as INPA.
Low-Pass Filter Terminal for the Phase Output.
Single-Ended Output Proportional to the Phase Difference between INPA
and INPB.
Feedback Pin for Scaling of VPHS Output Voltage in Measurement Mode.
Apply a setpoint voltage for controller mode.
Internally-Generated Reference Voltage (1.8 V Nominal).
Feedback Pin for Scaling of VMAG Output Voltage Measurement Mode.
Accepts a set point voltage in controller mode.
Single-Ended Output. Output voltage proportional to the decibel ratio
of signals applied to INPA and INPB.
Low-Pass Filter Terminal for the Magnitude Output.

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 AD8302 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.
