GENERAL DESCRIPTION
The ADuM4151/ADuM4152/ADuM41531 are 7-channel,
SPIsolator™ digital isolators 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 17 MHz. These channels operate with 14 ns
propagation delay and 1 ns jitter to optimize timing for SPI.
The ADuM4151/ADuM4152/ADuM4153 isolators also provide
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 250 kbps data rate with
up to 2.5 µs of jitter in the low speed channels.

SPECIFICATIONS
ELECTRICAL CHARACTERISTICS—5 V OPERATION
All typical specifications are at TA = 25°C and VDD1 = VDD2 = 5 V. Minimum and maximum specifications apply over the entire
recommended operation range: 4.5 V ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 V, and −40°C ≤ TA ≤ +125°C, unless otherwise noted. Switching
specifications are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted.

1 Codirectional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation barrier.
2 The MSS signal is glitch filtered in both speed grades, whereas the other fast signals are not glitch filtered in the B grade. To guarantee that MSS reaches the output
ahead of another fast signal, set up MSS prior to the competing signal by different times depending on speed grade.
3 VIx = VIA, VIB, or VIC.
4 An internal asynchronous clock not available to users samples the low speed signals. If edge sequence in codirectional channels is critical to the end application, the
leading pulse must be at least 1 tVIx SKEW time ahead of a later pulse to guarantee the correct order or simultaneous arrival at the output.
