The ADuM3150 is a six-channel SPIsolator™ digital isolator optimized for isolated serial peripheral interfaces (SPI). 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 channels support SPI clock rates of up to 17 MHz.
The ADuM3150 isolator also provides two additional independent low 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 also supports a delay clock output on the master side of the device. This output can be used with an additional SPI port on the master to support 40 MHz clock performance.
