Description
Do Not Connect. Used for factory test.
AC Input to the RMS Core.
Output Connection for the FET Input Buffer Amplifier.
Inverting Input to the FET Input Buffer Amplifier.
Noninverting Input to the FET Input Buffer Amplifier.
Optional 10 kΩ Precision Gain Resistor.
Do Not Connect. Used for factory test.
Internal 16 kΩ Current-to-Voltage Resistor. Connect to ground for voltage output at Pin 9; leave unconnected
for current output at Pin 9.
Voltage or Current Output of the RMS Core.
Negative Supply Rail.
Half Supply Node. Leave open for single-supply operation.
Noninverting Input of the Optional Precision Output Buffer. OBUFIN+ is typically connected to OUT.
Inverting Input of the Optional Precision Output Buffer. OBUFIN− is typically connected to OBUFOUT.
Low Impedance Output for ADC or Other Loads.
Power Pin for the Output Buffer.
