5V, 6-Channel, SPIsolator Digital Isolator for SPI with Delay Clock

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.
