The ADuM1420 quad isolated gate driver provides four independent high‑side and low‑side outputs with true galvanic isolation. Each channel can handle up to ±700 V peak differential voltage and 0.1 A peak output current, making it suitable for plasma display modules and other high‑voltage applications. The device operates from a 4.5‑5.5 V input supply and 12‑18 V output supplies, with a maximum switching frequency of 5 Mbps.
The datasheet includes full electrical characteristics, package dimensions, safety‑related specifications, and typical performance graphs. Recommended operating temperature ranges from –40 °C to +105 °C, and the part meets UL 1577 insulation standards with a 1667 V rms dielectric rating. Pin configurations, functional block diagram, and power‑up/down behavior are also documented.
