Device identity and board function
The LTC6820HMS#PBF is an isoSPI isolated communications interface from Analog Devices, part of the isoSPI series. It translates standard SPI signals across an isolation barrier using a single twisted-pair cable, eliminating the need for optocouplers or dedicated isolated SPI buffers on each channel. The 16-MSOP package (0.118" body width, 3.00mm) fits a tight PCB footprint typical of isolated interface nodes.
Active lifecycle and compliance
The device is ROHS3 compliant, meeting the latest EU restriction directive for lead-free soldering processes. No special handling exemptions are required for reflow assembly.
Package and supply voltage fit
The 16-TFSOP package (0.118" width, 3.00mm) with a 0.50mm pin pitch requires a standard surface-mount footprint.
Sourcing and cross-reference note
The closest functional peer is the LTC6820HUD#PBF, which shares the same isoSPI core, SPI interface, and 2.7V-5.5V supply, but is packaged in a 16-QFN (3mm × 3mm) rather than the 16-MSOP. The QFN variant has a different land pattern and exposed thermal pad — a board spin is required to swap between them.
