The LTC4332 is a point-to-point rugged SPI extender designed for operation in high noise industrial environments over long distances. Using a ±60V fault protected differential transceiver, the LTC4332 can transmit SPI data, including an interrupt signal, up to 2MHz over two twisted pair cables. The extended common mode range and high common mode rejection on the differential link provides tolerance to large ground differences between nodes.The LTC4332 provides a control interface using a separate slave select for configuration and fault monitoring.ApplicationsIndustrial Control and SensorsLighting and Sound System Control
