ADUM4150: 5kV, Dedicated Isolators for High-Speed SPI Interfaces (with 1/1 Aux channel directionality)

The ADuM4150 is a 5kV rms, 6-channel, SPIsolator™ digital isolator optimized for isolated serial peripheral interfaces (SPIs). (3.75kV rms model available). Based on the Analog Devices, Inc., iCoupler® chip scale transformer technology, 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 delay and 1 ns jitter to optimize timing for SPI.

The ADuM4150 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 ADuM4150 supports a delay clock output on the master side of the device. This output can be used with an additional clocked port on the master to support 40 MHz clock performance. See the Delay Clock section for more information.
