Performance/Functional Specifications
Typical at T
A
= +25°C and supply voltage = +5V using the single-ended input circuit,
unless otherwise noted.
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.
BCD outputs are optional and must be specified in the part number.
See Ordering Information.
Includes high-intensity and BCD-output models.

Technical Notes
1. ANALOG COMMON (Pin 10):
This pin is an internal, low-noise
ground for the DMS-40PC. It is internally connected to pin 3
(5V RETURN).
Do not connect pin 10 to either pin 3 or your
system ground
as this will create a ground loop and possibly result
in erroneous readings.
2. REFERENCE INPUT/OUTPUT (Pin 7):
This pin accesses the
meter's internal reference and is used during the factory calibration
procedure. Pin 7 should be left open in most common applications.
It can be used in certain "ratiometric" applications in which it is
desirable for the meter’s reference to track an external reference.
See Ap Note 3 in the DATEL Panel Meter Catalog for more details.
3. DISPLAY TEST (Pin 2):
Connecting pin 2 to ground (pin 3, 5V
RETURN) will activate all LED segments, and the display will read
"–18888" regardless of the actual applied input. To reduce self-
heating,
the display should not be left in the "test" mode for
more than 10 seconds
. This pin should be left open if unused.
4. DISPLAY HOLD (Pin 9):
For normal operation, this pin should be
left open. To hold the meter’s last reading and display it continu-
ously, tie pin 9 to ground (pin 3, 5V RETURN).
5. Decimal Point Placement:
The location of the decimal point is
user-selectable, and the decimal point control pins (DP1-DP4) are
active low functions. Select the appropriate decimal point by tying
pin 4, 5, 6 or 8 to pin 3 (5V RETURN). Unused decimal point
location pins should be left open.
