Analog Devices Inc. ADuM415x SPIsolator™ Digital Isolators
Analog Devices ADuM415x SPIsolator™ Digital Isolators feature iCoupler® technology and allow designers to implement isolation in designs without the cost, size, power, performance, and reliability constraints associated with optocouplers. The SPIsolator™ digital isolators are dedicated serial peripheral interface (SPI) isolators that have a small footprint, simple design, fast speed, and high data integrity. Unlike optocoupler and previous digital isolator solutions, SPIsolator Digital Isolators offer the ability to increase performance and lower cost while reducing board space using a single compact form factor.
The ADuM415x product offering consists of the following product series.
• ADuM4150 Dedicated Isolators for High-Speed SPI Interfaces (with 1/1 Aux channel directionality)
• ADUM4151 Dedicated Isolators for SPI Interfaces (with 2/1 Aux channel directionality)
• ADUM4152 Dedicated Isolators for SPI Interfaces (with 1/2 Aux channel directionality)
• ADUM4153 Dedicated Isolators for SPI Interfaces (with 0/3 Aux channel directionality)
• ADUM4154 Dedicated Isolators for SPI Interfaces (with Control for up to 4 Slaves)
