The ADuM3400/ADuM3401/ADuM3402 are high performance quad-channel digital isolators that provide enhanced system-level ESD reliability. These devices are based on Analog Devices' industry-leading isolation technology and offer outstanding ESD performance, low power consumption, and high data rates.
The ADuM340x family are quad‑channel digital isolators that combine high‑speed CMOS with monolithic air‑core transformer technology. They offer bidirectional communication, level translation between 3 V and 5 V, and high‑temperature operation up to 105 °C.
Key specifications include supply currents as low as 0.57 mA per channel (typical 0.83 mA at 5 V), maximum data rates up to 90 Mbps (CRW grade), propagation delays as low as 20 ns, and common‑mode transient immunity greater than 25 kV/µs. The devices are suitable for general‑purpose multichannel isolation, RS‑232/422/485 transceivers, and industrial field‑bus isolation.
