PIN-TO-PIN ALTERNATIVE
NSi8220N0-DSPR is a Chinese-manufactured pin-to-pin drop-in replacement for ADuM1200 / ISO7720 / Si8620 (Analog Devices / Texas Instruments / Skyworks).
Analog Devices / TI / Skyworks cross-reference in the same footprint, with lower propagation delay and roughly half the price.
NSi8220N0-DSPR — Alternative to ADuM1200 / ISO7720 / Si8620
NSi8220N0-DSPR from Novosense {BRAND} is supplied by JTDZ Tech (Shenzhen Jingteng Electronics) as a cost-effective, short-lead-time alternative to the imported ADuM1200 / ISO7720 / Si8620 (Analog Devices / Texas Instruments / Skyworks). Chinese-sourced semiconductors have moved well beyond "cheap substitute" status: the parts below are production-validated in industrial, automotive and consumer designs, and they remove both the allocation risk and the long lead times that come with imported.

What to check before substituting NSi8220N0-DSPR for ADuM1200
- Package and pinout are compatible with ADuM1200-class parts, so the footprint is unchanged and propagation delay is lower.
- Channel direction must match your design: NSi8220 is 2 forward / 0 reverse, which corresponds to ADuM1200. If your design uses ADuM1201 (1 forward / 1 reverse), choose the NSi8221 or NSi8222 instead.
- Wide 2.5 V to 5.5 V supply on both sides simplifies level shifting between 3.3 V and 5 V logic.
- Isolation barrier lifetime is specified above 60 years.
Typical Applications
- Industrial automation and motor control
- Isolated SPI, RS-232 and RS-485 interfaces
- General-purpose multichannel isolation
- New-energy and power conversion designs
