SPIsolator(TM) are dedicated SPI digital isolators. We've got your SPI bus covered with the introduction of these 5 new devices:
The highly integrated ADuM315x SPI digital isolator family simplifies the design of a complete SPI digital isolation solution by using just three components, compared to the 18 to 32 components required by alternative digital isolator- or optocoupler-based solutions. The ADuM315x family features low propagation delay and jitter in the CLK, MO-SI, MI-SO and SS channels to support SPI clock rates of up to 40 MHz. The new digital isolators also support the maximum sample rate for select ADI 12-, 16- and 18-bit precision A/D converters. The family has a 3.75 kVrms isolation rating and will be followed later in 2014 by SPIsolator devices rated to 5 kVrms.
The ADuM3150 supports a delayed clock output on the master side of the part that can be used with an additional general-purpose port on the master to support up to 40-MHz clock speeds.
The ADuM3151 , ADuM3152 and ADuM3153 provide four high-speed channels and three additional independent, low-data-rate channels in different configurations.
The ADuM3154 digital isolator provides a slave-select multiplexing system that allows up to four slave devices to be serviced from one isolator.
