Analog Devices Introduces New Family of Digital Isolator Devices Optimized for SPI Communications Applications
24 Juni 2014 - 3:00PM
Business Wire
Based on ADI’s award winning iCoupler® digital
isolator technology, the ADuM315x SPIsolator™ family delivers six
times the clock speed at as little as 1/5th the area and cost of
competing optocoupler and digital isolator solutions.
Analog Devices, Inc. (NASDAQ: ADI), a global leader in
high-performance signal processing technology, today introduced a
new family of digital isolator devices optimized for serial
peripheral interface (SPI) communications systems. The ADuM315x
SPIsolator™ digital isolator family is based on ADI’s award-winning
iCoupler® digital isolator technology, which has been shipped in
volumes exceeding one billion channels.
Supporting up to 40-MHz SPI clock speeds, the new digital
isolators are over six times faster, over 80 percent smaller and
cost as much as 85 percent less than competing optocoupler- or
digital isolator-based solutions. Faster SPI clock speeds
enable higher throughout in data acquisition systems, allowing
for higher performance and more rapid system response times. A high
level of functional integration provides system designers with a
simple solution for isolating high-speed SPI signals along with
commonly required low-speed status and control signals in a single
package.
The ADuM315x family supports a range of high-data-rate, SPI
communications applications including distributed control systems,
programmable logic controllers, and sensor monitors used in
industrial automation, instrumentation equipment and motor
controls. Watch a video of the ADuM315x SPIsolator family:

More About the ADuM315x SPIsolator Family
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.
