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
"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 preci-
sion reference actively trimmed at the factory. In normal opera-
tion, pin 8 must be tied to pin 7 to achieve all listed accuracy and
drift specifications.
Polycarbonate
0.75 ounces (21 grams)
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.
