GENERAL DESCRIPTION
The ADuM41541 is an SPIsolator™ digital isolator optimized for
a serial peripheral interface (SPI) that includes support for up to
four slave devices. Based on the Analog Devices, Inc., iCoupler®
chip scale transformer technology, the low propagation delay and
jitter in the CLK, MO/SI, MI/SO, and SS SPI bus signals support
SPI clock rates of up to 17 MHz.
The ADuM4154 isolator also provides a slave select multiplexing
system that allows up to four slave devices to be serviced from
one isolator. When a target slave is selected, the slave select
signal propagates to the desired output with low propagation
delay, allowing tight timing control. The isolated SSx is addressed
through a 250 kbps low speed, 2-channel address bus, allowing
the target slave device to be changed in as little as 2.5 µs.
