DP-650 Series
Miniature LCD Display Digital Panel Meters
Description
The DP-650 Series is an ultra-compact, low-power LCD meter requiring only 15mW of
power. This meter is ideal for applications requiring a highly reliable LCD display in a
small package. The snap-in bezel packaging enables easy and rapid installation of the
meter. The simplicity of design, overvoltage protection, and low power consumption all
contribute to the high reliability of this device.
Three input voltage ranges are available: 鹵200mV, 鹵2VDC, and 鹵20VDC. A 4-20mA
current input adapter (DP-670) is also offered. Automatic polarity, overrange indication,
adjustable decimal point, and display HOLD are standard features. The DP-650 Series
employs a dual slope integrating A/D converter, and operates from an internal 100mV
reference via a precision DC-to-DC converter. Typical accuracy is 鹵0.1%.

N o t e s
1. The connection shown utilizes differential inputs. For single-ended operation, INPUT(-) is
strapped to GND. If the signal is isolated from the power source, connect INPUT(-) to GND
either directly or through a 10K resistor network as shown to reduce common mode errors.
2. Display holds reading when HOLD is high (+5V). Readings are updated when HOLD is low
or floating.
3. The decimal point is user selectable by connecting the decimal point pins (4, 5, or 6) to DP
COM (pin 3).
4. Full-scale input span is adjusted prior to shipment. Further calibration is possible by adjusting
the trimpot mounted on the back of the DPM.
5. Unused pins should be left open.
