ADI公司的ADuM130D/ADuM130E/ADuM131D/ADuM131E是采用iCoupler®技术的三路数字隔离器.器件采用高速CMOS和单片空气芯变压器技术,其隔离性能要比光耦合器和其它耦合器要好得多.隔离电压高达3kV,最大时延是13ns,脉宽失真小于3ns,通路间匹配度优于3.0ns,主要用在通用多功能隔离以及SPI数据转换器隔热和工业现场隔离.本文介绍了ADuM13x系列产品主要特性,功能框图,以及评估板EVAL-ADuMQSEBZ主要特性,电路图,材料清单和PCB走线图.

The ADuM130D/ADuM130E/ADuM131D/ADuM131Eare triple-channel digital isolators based on Analog Devices, Inc., iCoupler® technology. Combining high speed, complementary metal-oxide semiconductor (CMOS) and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. The maximum propagation delay is 13 ns with a pulse width distortion of less than 3 ns at 5 V operation. Channel matching is tight at 3.0 ns maximum.
