6000 Vrms isolation and 100 Mbps — the SPI barrier that handles the dirty stuff
The LTM2895IY#PBF is a 9-channel SPI digital isolator from Analog Devices using magnetic coupling to push 100 Mbps across a 6000 Vrms isolation barrier. The channel configuration is 8 inputs on side 1 and 4 on side 2, with a mix of bidirectional and unidirectional paths — handy when you need chip-select and clock going one way and data returning the other on the same device. No integrated isolated power, so you'll need a separate DC-DC or an isolated module to feed the secondary side.
Where this thing lives — temperature and environment
The 6000 Vrms isolation is the headline number for medical equipment (patient-contact isolation) and high-voltage industrial bus interfaces where you need a solid safety barrier. Common-mode transient immunity is specified at 50 kV/µs minimum, which keeps data intact when a nearby contactor or IGBT switches.
Active lifecycle — no LTB panic
No end-of-life notices or last-time-buy deadlines to track. ROHS3 compliant, so it fits current assembly lines without exemption paperwork.
No isolated power onboard — plan the secondary rail
This isolator does not include an integrated isolated DC-DC converter. The secondary side of the barrier needs its own supply rail, either from a separate isolated module or a transformer-coupled design. That is typical for high-channel-count SPI isolators at this data rate — the trade-off is lower conducted emissions and more flexibility in choosing your secondary-side regulator.
