The ADUM4151ARIZ is a 7-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 17MHz. These channels operate with 14ns propagation delay and 1ns jitter to optimize timing for SPI. It also provides 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 250kbps data rate with up to 2.5µs of jitter in the low speed channels.
● Supports up to 17MHz SPI clock speed
● 4 High speed, low propagation delay, SPI signal isolation channels
● Three 250kbps data channels
● >25kV/µs High common-mode transient immunity
● 849V Peak maximum working insulation voltage
