Digital inputs which determine whether the PMU is forcing voltage or forcing current,
measuring current or measuring voltage.
Digital inputs which select one of the four current ranges.
Pins to resistors corresponding to ranges A through D. RF common pin to the resistors.
Analog input voltages which establish the lower and upper threshold level for the
measurement comparator.
Digital comparator outputs that indicate the DUT measurement is less than the upper
threshold (not high) and greater than the lower threshold (not low).
Analog voltage output that provides a real time monitor of either the measured voltage
or measured current level for the selected channel.
Digital input which disables IVMON output.
Analog input voltage that establishes the upper voltage clamp level.
Analog input voltage that establishes the lower voltage clamp level.
Digital input which places the FORCE output into high impedance.
Compensation pins that require an external capacitor connected between COMP1
and COMP2.
34, 27
Digital input selects an internal or external compensation capacitor.
