LTC6820 isoSPI Transceiver

Analog Devices Inc. LTC6820 isoSPI Transceiver provides bidirectional Serial Peripheral Interface (SPI) communications between two isolated devices through a single twisted-pair connection. The transmitting LTC6820 encodes logic states into signals transferred across an isolation barrier to another LTC6820. The receiving LTC6820 decodes the transmission and drives the slave bus to the appropriate logic states. A simple pulse transformer can bridge the isolation barrier to achieve hundreds of volts of isolation.
