TECHNICAL NOTES
RoHS Compliant Parts:
Add "-C" suffix to part number.
1. 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 specifica-
tions.
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. Decimal Point Placement:
The location of the decimal point is user-
selectable, and the decimal point control pins (DP1-DP3) are active
low functions. Select the appropriate decimal point by tying the
appropriate pin (pin 4, 5 or 6) to pin 3 (5V RETURN). Unused decimal
point location pins should be left open.
Hard wiring is preferable, however, you can use logic gates to
exercise dynamic control over the location of the decimal point if the
following drive conditions are met:

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.
See Technical Notes.
The DISPLAY HOLD function is optional on standard red and green LED models only.
* The driving gates must be able to sink this much current
