Murata DMS-20LCD Series 3½ Digit LCD Display Digital Panel Voltmeters Datasheet
The DMS-20LCD series provides sub‑miniature 3½‑digit LCD panel voltmeters (1.38" × 0.88" × 0.43") that operate from a single +5 V or +9 V supply. They feature four differential input ranges (+200 mV, +2 V, +20 V, +200 V), 800 kΩ minimum input impedance, 86 dB CMRR, and a low‑battery annunciator. Both backlit and non‑backlit versions are available, with backlight activated by grounding pin 9.
The document includes detailed performance specifications, mechanical dimensions, wiring diagrams, application examples such as differential and floating‑signal measurements, 4‑20 mA loop monitoring, and guidance on gain adjustment, soldering, and connector selection. Ordering information and optional accessories (bezel assemblies, evaluation board) are also provided.
