• RE: ADUM315x / ADUM3151 / ADUM3152 / ADUM3153 speedgrade question

    Hi Cristian, 

    The A-grade and B-grade are actually different. The SPI bus channels in the A-grade have a ~10ns glitch filter. In the B-grade, the glitch filter is removed from the clock, MOSI and MISO channels (the MSS channel has a glitch filter in both…

  • RE: ADUM3153 Multiple isolators on same spi bus?

    Hello James,

    We struggled with this function of the ADuM3151 during the design phase of this product, not from an implementation point of view, but from a compatibility point of view.  Many ADC's use the CSB as a convert start, and they can be transferring…

  • RE: Digital Isolator for SPI Interface

    Hi Sharvy,

    A  nominal supply voltage of 3.3V or 5.0V will power all SPIsolator Digital Isolators. The ADuM3150/ADuM3151/ADuM3152/ADuM3153 SPIsolator devices will cover your isolation requirement. The ADuM3150 device will support a SPI clock rate up to…

  • SPIsolator(TM) - What is a SPIsolator?

    SPIsolator(TM) are dedicated SPI digital isolators.  We've got your SPI bus covered with the introduction of these 5 new devices:

    The highly integrated ADuM315x SPI digital isolator family simplifies the design of a complete SPI digital isolation…

  • SPI总线在隔离系统中的处理方法

    SPI总线在隔离系统中的处理方法 by ADI_Amy

    SPI(串行外设接口)总线成为设计师宠儿的原因有多种。SPI总线支持高速工作模式,可在短距离内(如电路板芯片间)以最高60 Mbps的速率传输数据。总线在原理上很简单,由一个时钟、两条数据线路和一个芯片选择信号构成。由于数据出现在时钟的一个相位上并在相反相位读回,因此,在速率上出现延迟和失配的几率非常大。最后,总线是由单向线路构成的,这种设计简化了其在微处理器中的实现方式,消除了流程控制问题,非常适合光耦合器或数字隔离器的隔离应用,因为隔离器天生就属于单向器件…
