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.

Technical Notes

1. +1.23V REFERENCE OUTPUT (Pin 9): This pin is the output of the

meter’s precision +1.23V internal reference, and it is referenced to

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.

2. ANALOG COMMON (Pin 10): This pin is connected to an internal,

low-noise, "relative" ground. It is used in certain differential and

"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.

3. REFERENCE OUTPUT (Pin 8) and INPUT (Pin 7): Pin 8 is a

precision reference actively trimmed at the factory. In normal

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

and drift specifications.
