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. 2JEDEC 1S Standard (2-layer) board data. PIN CONFIGURATION TOP VIEW (Not to Scale) 1 COMM AD8302 INPA OFSA VPOS OFSB INPB COMM MFLT VMAG MSET VREF PSET VPHS PFLT 2 3 4 5 6 7 14 13 12 11 10 9 8 PIN FUNCTION DESCRIPTIONS Equivalent Pin No. Mnemonic Function Circuit 1, 7 COMM Device Common. Connect to low impedance ground. 2 INPA High Input Impedance to Channel A. Must be ac-coupled. Circuit A 3 OFSA A capacitor to ground at this pin sets the offset compensation filter corner Circuit A and provides input decoupling. 4 VPOS Voltage Supply (VS), 2.7 V to 5.5 V 5 OFSB A capacitor to ground at this pin sets the offset compensation filter corner Circuit A and provides input decoupling. 6 INPB Input to Channel B. Same structure as INPA. Circuit A 8 PFLT Low Pass Filter Terminal for the Phase Output Circuit E 9 VPHS Single-Ended Output Proportional to the Phase Difference between INPA Circuit B and INPB. 10 PSET Feedback Pin for Scaling of VPHS Output Voltage in Measurement Mode. Circuit D Apply a setpoint voltage for controller mode. 11 VREF Internally Generated Reference Voltage (1.8 V Nominal) Circuit C 12 MSET Feedback Pin for Scaling of VMAG Output Voltage Measurement Mode. Circuit D Accepts a set point voltage in controller mode. 13 VMAG Single-Ended Output. Output voltage proportional to the decibel ratio of signals applied to INPA and INPB. Circuit B 14 MFLT Low Pass Filter Terminal for the Magnitude Output Circuit E 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. WARNING!
