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.
