ADUM3154:  3.75 kV, 7-Channel Digital Isolators for SPI Interfaces

Product Details

Product Status:Recommended for New Designs

The ADuM3154 is a SPIsolator™ digital isolator optimized for a serial peripheral interface (SPI) that includes support for up to four slave devices. Based on the Analog Devices, Inc., iCoupler® chip scale transformer technology, the low propagation delay and jitter in the CLK, MO/SI, MI/SO, and SS channels support SPI clock rates of up to 17 MHz.

The ADuM3154 isolator also provides a slave select multiplexing system that allows up to four slave devices to be serviced from one isolator. The slave select system propagates to the desired output with full propagation speed, allowing tight timing control. The isolated SS multiplexer is addressed through a 250 kbps low speed dual port with 2.5 μs of setup time.

APPLICATIONS

  • Industrial programmable logic controllers (PLCs)
  • Sensor Isolation
