CMRR for all devices is 86dB, and inputs are overvoltage protected to ±250V. Each meter incorporates a precision, ultra-stable voltage reference and is factory calibrated prior to encapsulation. The small size (2.17" x 0.92" x 0.56") of DMS-30DR meters is achieved by integrating their display, Autodim display drivers, light sensor, reference circuit, and A/D converter into in a rugged epoxy-encapsulated assembly. The device’s 12-pin, component-like, DIP package is both vibra- tion and moisture proof, making them ideal for harsh environments. Each package incorporates a built-in color fi lter and bezel, and is easily mounted in either panels or pc boards. 1 12 +5V SUPPLY +5V +5V (–) INPUT LO R2 (1) 0.01μF EXTERNAL ABDRJIGUSHTTMNEESNST 2 CONDVCE/DRCTER –5V –5V R1 11 (+) INPUT HI 909k 3 +5V A/D 10 ANALOG 5V RETURN CONVERTER COMMON –5V 1.225V 0 Vdc DATA REF. 4 9 DP 3 +1.225V REFERENCE OUT 1.82k 5 8 DP 2 REFERENCE OUT LIGHT +5V SENSOR 7 6 REFERENCE IN DP 1 (1)R2 is not used on ±200mV (-0) models or ±2V (-1) models.
