The ADuM3150 is a 6-channel SPIsolator™ digital isolator optimized for isolated serial peripheral interfaces (SPIs). Basedon the Analog Devices, Inc., iCoupler® chip scale transformertechnology, the low propagation delay in the CLK, MO/SI,MI/SO, and SS SPI bus signals supports SPI clock rates of up to 17 MHz. These channels operate with 14 ns propagation delayand 1 ns jitter to optimize timing for SPI.The ADuM3150 isolator also provides two additional independentlow data rate isolation channels, one channel in each direction. Data in the slow channels is sampled and serialized for a 250 kbps data rate with 2.5 μs of jitter.The ADuM3150 supports a delay clock output on the master side of the device.
