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.
- Industrial programmable logic controllers (PLCs)
- Sensor isolation
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The board follows best printed circuit board (PCB) design practices for 4-layer boards, including a full power and ground plane on each side of the isolation barrier. No other EMI or noise mitigation design features are included on this board. In cases of very high speed operation or when ultralow emissions are required, refer to the AN-1109 application note for additional board layout techniques.
