LTC68201 Rev CFor more information FeedbackTYPICAL APPLICATION FEATURESDESCRIPTIONisoSPI Isolated Communications InterfaceThe LT C 6820 provides bidirectional SPI communications between two isolated Devices through a single twisted-pair connection. Each LTC6820 encodes logic states into signals that are transmitted across an isolation barrier to another LTC6820 . The receiving LTC6820 decodes the transmission and drives the slave bus to the appropri-ate logic states. The isolation barrier can be bridged by a simple pulse transformer to achieve hundreds of volts of LTC6820 drives differential signals using matched source and sink currents, eliminating the requirement for a transformer center tap and reducing EMI. Precision window comparators in the receiver detect the differential signals.
