Analog Devices ADuM1234 Isolated Half-Bridge Driver Datasheet
The ADuM1234 is an isolated, precision half‑bridge driver that provides independent high‑side and low‑side outputs with up to ±700 V isolation. It uses Analog Devices' iCoupler technology to achieve high speed CMOS performance without the drawbacks of optocouplers.
Key specifications include a 0.1 A peak output current, 5 MHz maximum switching frequency, 2500 Vrms isolation voltage, and an operating temperature range of –40 °C to +105 °C. The device is suited for isolated IGBT/MOSFET gate drives, industrial inverters, switching power supplies, and plasma displays.
