ADuM4154 Series SPIsolator Digital Isolators, Analog Devices

The ADuM4154 series, from Analog Devices, are 7-channel, multiple slave, digital isolator optimized for a serial peripheral interface (SPI). The ADuM4154 includes support for up to four slave devices which minimises part count, reducing size and costs. They form a part of the SPIsolator™ family of devices.
Based on the Analog Devices’ 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 17MHz.
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 250kbps low speed, 2-channel address bus, allowing the target slave device to be changed in as little as 2.5μs.

Features of the ADuM4154 SPIsolator™ :
- Supports up to 17 MHz SPI clock speed
- 4 high speed, low propagation delay, SPI signal isolation channels
- Supports up to 4 slave devices
- 20-lead SOIC_IC package with 8.3 mm creepage
- High temperature operation: 125°C
- High common-mode transient immunity: >25 kV/μs

SPIsolator™ Digital Isolators
Utilising Analog Devices’ iCoupler® Technology, the SPIsolator™ digital isolators are dedicated SPI isolators. They offer a small footprint, simple design, fast speed and high data integrity. Different to optocoupler and previous digital isolator solutions, the SPIsolator ™ family offers the ability to increase performance and lower cost all while reducing board space by utilizing a single compact form factor.
