ADBMS6821/ADBMS6822 isoSPI™ Transceivers

Analog Devices ADBMS6821/ADBMS6822 Single/Dual isoSPI™ Transceivers feature the ADBMS6821 (single) and ADBMS6822 (dual) with bidirectional isolated serial-port interface (isoSPI) communications between two isolated devices via a single twisted pair connection for each data link. Each transceiver encodes logic states into signals transmitted across an isolation barrier to another transceiver. The receiving device decodes the transmission and drives the peripheral bus to the appropriate logic states. Capacitors or pulse transformers can bridge the isolation barrier to achieve hundreds of volts of isolation.
