ADUM3151ARSZ Product Details

Analog Devices ADuM3151 SPIsolator Digital Isolators consists of 7-channel dedicated 3.75kVrms digital isolators optimized for isolated serial peripheral interfaces (SPIs) with 2/1 aux channel directionality. Developed using Analog Devices, Inc., iCoupler� chip scale transformer technology, ADuM3151's low propagation delay in the CLK, MO/SI, MI/SO, and SS SPI bus signals supports SPI clock rates of up to 17MHz. These channels operate with 14ns propagation delay and 1ns jitter to optimize timing for SPI. The ADuM3151 isolators also provides two additional independent low data rate isolation channels, one channel in each direction. Data in the slow channels is sampled and serialized for a 250kbps data rate with 2.5s of jitter.

Analog Devices ADuM315x SPIsolator Digital Isolators feature iCoupler� technology and allow designers to implement isolation in designs without the cost, size, power, performance, and reliability constraints associated with optocouplers.  The SPIsolator digital isolators are dedicated a serial peripheral interface (SPI) isolators that have a small footprint, simple design, fast speed, and high data integrity. Unlike optocoupler and previous digital isolator solutions, the SPIsolator Digital Isolators offer the ability to increase performance and lower cost while reducing board space using a single compact form factor.


  • Supports up to 17MHz SPI clock speed
  • 4 High speed, low propagation delay, SPI signal isolation channels
  • Three 250kbps data channels
  • High temperature operation
  • High common-mode transient immunity (>25kV/µs)


  • Industrial programmable logic controllers (PLCs)
  • Sensor isolation
