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

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 ADuM3151/ADuM3152/ADuM3153 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.
