ADUM2401ARWZ-RL

The ADuM2401ARWZ-RL is a quad-channel digital isolator from Analog Devices Inc., built using iCoupler® technology. It provides robust isolation for general-purpose, high-voltage multichannel applications, including medical equipment, motor drives, and power supplies.

This isolator supports high data rates up to 90 Mbps (NRZ) and operates bidirectionally. It is designed for flexible voltage compatibility, functioning with supply voltages from 2.7V to 5.5V and enabling 3V/5V level translation. Key electrical characteristics include precise timing with a maximum pulse width distortion of 2 ns and channel-to-channel matching of 2 ns. It also boasts high common-mode transient immunity exceeding 25 kV/µs.

The device operates reliably at high temperatures up to 105°C. It is available in a 16-lead SOIC wide body package, with an enhanced creepage version also offered. Safety and regulatory approvals are noted for the enhanced creepage package, including UL recognition, CSA acceptance, and various IEC standards.

This component offers a low-power alternative to traditional optocouplers, eliminating concerns about current transfer ratios and temperature/lifetime effects. The output enable function provides additional control.
