What this SPI isolator brings to the board
The Analog Devices LTM2886CY-3S#PBF is a 6-channel SPI digital isolator with an integrated isolated DC-DC converter — one part handles both signal isolation and the isolated-side power rail, saving board space and eliminating the need for a separate isolated supply module. Capacitive coupling technology keeps propagation delay to 100 ns max and common-mode transient immunity at 30 kV/µs, so it holds data integrity across a galvanic barrier even in noisy environments like motor drives or industrial fieldbuses.
Data rate and timing — what 8 MHz means for the SPI bus
The part supports SPI clock rates up to 8 MHz. At 8 MHz the 100 ns propagation delay leaves margin for most bus topologies.
Temperature grade and environment
Rated for 0°C to 70°C commercial temperature range. This limits the part to indoor, temperature-controlled environments — office equipment, lab instrumentation, test and measurement, industrial control cabinets with active cooling. Not suited for outdoor telecom cabinets, engine bays, or downhole tools where the ambient exceeds 70°C.
Lifecycle and compliance
The LTM2886CY-3S#PBF carries an active lifecycle status. It is ROHS3 compliant.
