The ADuM4151/ADuM4152/ADuM4153 are 7-channel, SPIsolator digital isolators optimized for isolated serial peripheral interfaces (SPIs).(3.75kV 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 SPI 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 ADuM4151/ADuM4152/ADuM4153 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.

Applications

  • Industrial programmable logic controllers (PLCs)
  • Sensor isolation

Features and Benefits

  • Access to all seven data channels
  • Multiple connection options
  • Support for Tektronix active probes
  • Provision for cable terminations
  • Support for PCB edge-mounted coaxial connectors
  • Easy configuration
  • Installed SPIsolator® digital isolator: ADuM3151BRSZ in the 20-lead SSOP package

Product Detail

The EVAL-ADuM3151Z supports the parts listed in the supported models section, which are, 7-channel, data direction variants of SPIsolator® isolators optimized for use in SPI applications. They include three low speed channels for axillary functions, which are not timing critical. The evaluation board provides a JEDEC standard 20-lead SSOP pad layout, support for signal distribution, loopback, and loads referenced to VDDx or GNDx, as well as optimal bypass capacitance. Signal sources can be wired onto the board as well as brought onto the board through edge-mounted SMA connectors (sold separately) or terminal blocks for power connections. The board includes 200 mil header positions for compatibility with Tektronix active probes.

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.
