The ADuM41541 is an SPIsolator™ digital isolator optimized for a serial peripheral interface (SPI) that includes support for up to four peripheral devices. Based on the Analog Devices, Inc., iCoupler® chip scale transformer technology, the low propagation delay and jitter in the CLK, MO/SI, MI/SO, and SS SPI bus signals support SPI clock rates of up to 17 MHz. The ADuM4154 isolator also provides a peripheral select multiplexing system that allows up to four peripheral devices to be serviced from one isolator. When a target peripheral is selected, the peripheral select signal propagates to the desired output with low propagation delay, allowing tight timing control. The isolated SSx is addressed through a 250 kbps low speed, 2-channel address bus, allowing the target peripheral device to be changed in as little as 2.5 μs.
