The ADuM41501 is a 6-channel, SPIsolator™ digital isolator 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, and SS SPI bus signals supports SPI clock rates of up to 17 MHz. These channels operate with 13 ns propagation delay and 1 ns jitter to optimize timing for SPI.

The ADuM4150 isolator 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 250 kbps data rate with 2.5 μs of jitter.

The ADuM4150 supports a delay clock output on the primary side of the device. This output can be used with an additional clocked port on the primary to support 40 MHz clock performance. See the Delay Clock section for more information.

Analog Devices is in the process of updating documentation to provide terminology and language that is culturally appropriate. This is a process with a wide scope and will be phased in as quickly as possible. Thank you for your patience.

Product Details

The EVAL-ADuM3150Z supports the ADuM3150ARSZ and ADuM3150BRSZ, which are 6-channel SPIsolator® isolators optimized for use in SPI applications. They include two low speed channels and a clock delay channel for the implementation of 40 MHz SPI data transfers. 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 EVAL-ADuM3150Z evaluation board can be used to evaluate the ADuM4150ARIZ and the ADuM4150BRIZ devices. Although the pad layout on the EVAL-ADuM3150Z evaluation board does not support the ADuM4150ARIZ and the ADuM4150BRIZ 20-lead SOIC_IC packages, these devices can be evaluated with the ADuM3150ARSZ or the ADuM3150BRSZ. The ADuM4150ARIZ and ADuM3150ARSZ differ by package and isolation capabilities, but are functionally equivalent for evaluation. The same is true for the ADuM4150BRIZ and ADuM3150BRSZ devices.


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 electromagnetic interference (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.


For full details, see the ADuM3150 data sheet, which must be used in conjunction with UG-719 when using the EVAL- ADuM3150Z evaluation board.
