ADUM3151BRSZ                       DESCRIPTION

The ADuM3151/ADuM3152/ADuM31531 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.
