Applies for transient or continuous overvoltages applied to (+) INPUT HI (pin 11)
with (–) INPUT LO (pin 12) properly connected. Pin 12 is not overvoltage protected
(see Figure 1). Voltages applied to pin 12 should not exceed the supply voltage.

ANALOG COMMON (pin 10) which sits at a potential of approxi-
mately +2V. This output should be buffered if used to drive external
loads since sourcing more than 15µA from pin 9 can affect both the
initial accuracy and temperature drift of the meter.

"floating" measurements as described in the Applications section of
this data sheet and Ap Note 3 of the DATEL Panel Meter Catalog.
Pin 10 should not be connected to pin 3 (5V RETURN) or to your
system’s analog ground.

operation, pin 8 must be tied to pin 7 to achieve all listed accuracy
