General-purpose digital isolator for noisy environments
The Maxim Integrated MAX12931BASA+ is a two-channel, unidirectional digital isolator using capacitive coupling to pass signals across a 3750Vrms isolation barrier. It handles data rates up to 25Mbps.
What the key ratings mean for your BOM
The 3750Vrms isolation voltage is the primary safety spec. The 25Mbps data rate is adequate for most sensor and control links.
Temperature grade and deployment environment
The capacitive coupling technology has no LED wear-out mechanism, so it holds up over temperature cycling better than optocoupler-based isolators. The 8-SOIC package is a standard footprint — no special layout beyond the usual 8mm creepage clearance for 3750Vrms.
