2 / 6 page 2 DMS-20PC 3 ½ DIGIT , LED DISPLA Y DIGIT AL P ANEL V O L TMETERS Performance/Functional Specifications Typical at TA = +25°C and supply voltage = +5V using the single-ended input circuit, unless otherwise noted. ➀ 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. ➁ See Technical Notes. ➂ The DISPLAY HOLD function is optional on standard red and green LED models only. See Ordering Information. Leave blank for standard models. Add -H for DISPLAY HOLD option (available on standard red and green LED models only). DMS-20PC - 1 - RS LED Color: AS = Standard Amber GS = Standard Green OS = Standard Orange RS = Standard Red YS = Standard Yellow RH = High-Intensity Red RL = Low-Power Red Accessories: DMS-20-CP Panel cutout punch DMS-BZL3 DMS-20 bezel assembly DMS-BZL4 DMS-20 bezel assembly with sealing gasket DMS-EB2 Application/evaluation board with standard MOLEX connector, decimal point solder pads and attenuation resistor pads. Technical Notes 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 specifications. 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: Model Applied "0" Voltage Load Current* DMS-20PC-X-RL +0.05V max. 0.7mA max. All Others +0.4V max. 6mA max. * The driving gates must be able to sink this much current (IOL) with a logic "0" output.
