Description
AI
The ADuM3151/ADuM3152/ADuM3153are 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, andSSSPI 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.ApplicationsIndustrial programmable logic controllers (PLCs)Sensor isolation
