ANALOG DEVICES ADUM4150ARIZ

ADuM4150 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 17MHz. This channel operate with 13ns propagation delay and 1ns jitter to optimize timing for SPI. It is 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 250kbps data rate with 2.5µs of jitter. This supports a delay clock output on the host side of the device. Application includes industrial programmable logic controllers (PLC), sensor isolation.
