The Analog Devices LTC6820IMS#PBF is a bidirectional isolated communications interface designed to carry SPI data across an isolation barrier using a single twisted pair. It simplifies isolated data transfer by encoding SPI signals into a differential format. The device operates from a 2.7V to 5.5V supply and is offered in a 16-MSOP surface-mount package.
- Reliable Isolated SPI: Provides a proven method for sending SPI data across isolation boundaries.
- Compact MSOP Footprint: Saves board space while maintaining full functionality.
- Flexible Supply Range: Works with 2.7V to 5.5V supplies, simplifying power design.
- Reduced BOM Cost: Replaces multiple optocouplers with a single IC and twisted-pair cable.
Isolated Industrial Controllers
The LTC6820IMS#PBF provides a robust isolated SPI link between PLCs and remote I/O modules, ensuring reliable communication in harsh industrial environments with high electromagnetic interference.
Battery Monitoring Systems
In large battery stacks, this device isolates the cell monitoring ICs from the main battery management controller, allowing safe SPI communication across the high-voltage isolation boundary.
Medical Device Isolation
For medical devices requiring patient isolation, the LTC6820 enables SPI communication between the isolated patient-side circuitry and the non-isolated processing side, meeting safety standards.
Grid-Tied Inverters
Solar and wind inverters use this interface to isolate the DSP controller from the power stage, providing a reliable communication path for real-time control and monitoring.
Test and Measurement Equipment
Benchtop instruments benefit from isolated SPI channels to communicate with floating measurement front-ends, improving accuracy by eliminating ground loops.
