It delivers 3000Vrms galvanic isolation across a 3V to 5.5V supply range, with one channel on side 1 and one on side 2 — a 1/1 input split that suits a single isolated signal pair (e.g., SPI clock and data, or a UART TX/RX). The 1Mbps data rate and 50ns max propagation delay keep timing tight for most industrial serial links, while the 25kV/µs common-mode transient immunity means it won't glitch on a motor-drive PWM edge. ## Why 25kV/µs CMTI matters on a motor drive or PSU Common-mode transients — fast voltage swings between the two ground planes — are the main failure mode for isolated data links in inverter-fed motor drives, switch-mode power supplies, and solar inverters. The ADUM1286ARZ's minimum 25kV/µs CMTI means the output stays valid when the ground plane jumps hundreds of volts in a few nanoseconds. If you have ever seen a bit error on a CAN or RS-485 isolator that traced back to a switching-node edge, this is the spec that fixes it. ## Package and temperature: one less worry on the BOM ROHS3 compliant and active in production, so no LTB pressure on the supply plan.","metaTitle":"ADUM1286ARZ Digital Isolator, 3000Vrms, 2-Ch, 1Mbps, 8-SOIC","metaDescription":"ADUM1286ARZ iCoupler 2-channel digital isolator, 3000Vrms isolation, 1Mbps data rate, 25kV/µs CMTI.
