ADUM342E1BRWZ-RL Question (Level Shifting & Isolation)

Category: Hardware
Product Number: ADUM342E1BRWZ-RL

Hi, AD

I want to level shift the 3.3V Level UART Signal to 5V and do I/O Isolation of the UART Signal. Can I use this ADUM342E1BRWZ-RL chip?
If available, request a Sample Schematic.

  • Hi Shane, 

    The two sides of the ADuM34xE are completely independent. You can supply VDD1 and VDD2 with the level that suites the application (provided its within the 2.25-5.5V recommended operating range) . 3.3V for VDD1 and 5V for VDD2 is fine.

    The input/output channel voltage levels scale with the local VDD pin. 

    Regards,

    Jason
