ADUM3151 3.75 kV, Dedicated Isolators for SPI Interfaces (with 2/1 Aux channel directionality)
The ADuM3151/ADuM3152/ADuM3153 are 3.75kV rms, 7-channel SPIsolator™ digital isolators optimized for isolated serial peripheral interfaces (SPIs). (5kV rms model available). Based on the Analog Devices, Inc., iCoupler® chip scale transformer technology, the low propagation delay in the CLK, MO/SI, MI/SO, and SS channels 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.
