Overview
Data Sheet 5 kV, 7-Channel, SPIsolator Digital Isolators for SPI ADuM4151/ADuM4152/ADuM4153 12370-001 FEATURES Supports up to 17 MHz SPI clock speed 4 high speed, low propagation delay, SPI signal isolation channels Three 250 kbps data channels 20-lead SOIC_IC package with 8.
3 mm creepage High temperature operation: 125°C High common-mode transient immunity: >25 kV/µs Safety and regulatory approvals UL recognition per UL 1577 5000 V rms for 1 minute SOIC long package CSA Component Acceptance Notice 5A VDE certificate of conformity DIN V VDE V 0884-10 (VDE V 0884-10):2006-12 Maximum working insulation voltage (VIORM): 849 V peak APPLICATIONS Industrial programmable logic controllers (PLCs) Sensor isolation 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.
