GENERAL 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.
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.
