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: 200mV, 2VDC, and 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 0.1%.

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.

User-selectable decimal point

Hold-display function

3. The decimal point is user selectable by connecting the decimal point pins (4, 5, or 6) to DP

COM (pin 3).

Overvoltage protection

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.

Quantity discounts

5. Unused pins should be left open.
