GENERAL DESCRIPTION

The ADuM4151/ADuM4152/ADuM41531 are 7-channel, SPIsolator? digital isolators optimized for isolated serial peripheral interfaces (SPIs). 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 ADuM4151/ADuM4152/ADuM4153 isolators also provide three additional independent low data rate isolation channels in three different channel direction combinations. Data in the slow channels is sampled and serialized for a 250 kbps data rate with up to 2.5 μs of jitter in the low speed channels.
