ADUM130D0BRZ Digital Isolator – Avalon 921 Hashboard Repair
The ADUM130D0BRZ is a three-channel digital isolator in a 16-SOIC package, used on Avalon 921 hashboards for ASIC-chain signal isolation. Built on high-speed CMOS + monolithic transformer technology — the iCoupler architecture — for clean signal transfer with superior noise immunity vs legacy optocoupler designs.
Headline specs: 150 Mbps data rate, 2.7 V – 5.5 V supply range (wide system compatibility), and 3000 Vrms voltage isolation. Three independent channels in flexible configurations cover the standard Avalon 921 housekeeping bus translation.
Typical Failure Modes Solved
- Avalon 921 hashboard signal failure — broken isolator dropping data on the chain.
- Intermittent communication errors — degraded isolator under continuous load.
- Hot-failure recovery — replace after thermal-stress events.
- Production refurbishment — bulk isolator stock for Avalon rework lines.

FAQ — ADUM130D0BRZ Isolator
Q: 3 channels — all in one direction?
A: The ADUM130D variant has 3 forward channels (no reverse). For bidirectional isolation, use a different ADUM family variant (e.g. ADUM1250 hot-swap I²C).
Q: ADUM130D vs ADUM120N — interchangeable?
A: Different channel counts and configurations. Match the silk marking on your Avalon 921 board exactly.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
