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.
Listed spec applies to 5V-powered models only. For 9V-powered models, both
(–) INPUT LO (pin 12) and (+) INPUT HIGH (pin 11) must always be at least
1.5V above –BATTERY (pin 3) and at least 1.5V below +BATTERY (pin 1).
See Technical Notes.

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 approximately
+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 “float-
ing” measurements as described in the Applications section of this
data sheet and Ap Note 3 of the DATEL Panel Meter Catalog.
