Digital Isolator CMOS 4-CH 100Mbps 28-Pin SOIC W T/R
ADuM6423/24, ADuM6420A/21A/22A/21AW: Quad-Channel Isolator Families with Integrated DC-to-DC Converter
Quad-channel digital isolator family with isoPower®, integrated, isolated DC-to-DC converter based on iCoupler® technology that meets CISPR 32/EN 55032 Class B limits at a full load on a 2-layer printed circuit board (PCB) with ferrites.
The iCoupler chip scale transformer technology results in a small form factor, total isolation solution that provides four independent isolation channels.
● ADuM6423: 1:3 directionality
● ADuM6421A: 3:1 directionality
● ADuM6424: 0:4 directionality
● ADuM6422A: 2:2 directionality
● ADuM6420A: 4:0 directionality
● ADuM6421AW: automotive with 3:1 directionality
Key Features and Benefits
● Class B radiated emissions on a 2-layer PCB board eliminate the need of costly additional EMI mitigation techniques and simplifies the certification process
● Four high speed data channels with high common-mode transient immunity to maintain signal integrity in the harshest of environments with architecture designed for high 100 kV/µs CMTI and high immunity to electrical noise and magnetic interference
● Wide logic side input voltage range and high temperature operation of 125°C, capable of operating as low as 1.7 V and allowing direct connection to low power processors and FPGAs in high temp applications such as automotive and industrial
