DMS-20PC Series  
3½ Digit, LED Display, Low-Cost, Subminiature  
Digital Panel Voltmeters

FEATURES  
  
Lowest-cost LED meters  
DMS-20PC Series, 3½ Digit, LED Display, Digital Panel Voltmeters combine a preci-  
sion A/D converter; a factory-trimmed, highly stable, voltage reference; and a large  
(0.37"/9.4mm), easy-to-read LED display in a single package that is only slightly larger  
than the display itself. Displays are offered in either red, orange, amber, yellow, green or  
blue colors. High-intensity and low-power (35mW total) red LEDs are also optional.  
These low-cost meters are fully self-contained and fully functional. Their subminiature  
(1.38" x 0.88" x 0.48"), epoxy-encapsulated cases incorporate built-in color filters and  
bezels; are moisture and vibration proof; and function well in the harshest environments.  
Their 12-pin, dual-in-line configuration offers component-like, plug-in convenience and  
maximum versatility. Operating temperature range is 0 to +60°C.  
The meters come with one of four, differential, input voltage ranges: 200mV, 2V  
20V or 200V. Input impedance is a minimum 800kΩ. CMRR is typically 86dB (dc to  
60Hz), and CMV is 2V. Input overvoltage protection (on the non-inverting input) is 250V.  
Devices are fully calibrated at the factory to an accuracy of 1 count ( 0.05ꢀ of full scale  
range) and never require calibration or adjustment.  
  
Subminiature size:  
1.38" x 0.88" x 0.48" (35mm x 22mm x 12mm)  
  
Large (0.37"/9.4mm) LED display  
  
Choice of 6 LED colors  
  
High-intensity or low-power (7mA) red LEDs optional  
  
Epoxy-encapsulated, 12-pin DIP package with built-in  
color filter and bezel  
  
4 differential input voltage ranges  
  
Factory calibrated, 1 count accuracy  
  
Single +5V power supply  
A DISPLAY ENABLE function permits the display to be disabled for "power-down"  
operation. All models have a DISPLAY TEST function. Standard red LED models offer an  
optional DISPLAY HOLD function.  
Small size, low cost and adjustment-free reliability make the DMS-20PC Series the best  
choice for all your 3½ digit, LED, DPM applications.  
  
User-selectable decimal point placement  
  
DISPLAY ENABLE function for "power-down" mode  
  
DISPLAY TEST and HOLD (optional) functions  
  
0 to +60°C temperature range
