  • RE: DC coupling DRV8662EVM

    Resolved
    Thank you for the feedback - "I suspect something is damaged somewhere along the signal chain" - TI suggested the same thing but want to confirm - you replaced C4 & C5 with a 0-Ohm short to the input of U1 then applied Vdd/2 to offset the input…

  • DRV8662EVM source code question

    Resolved
    Other Parts Discussed in Thread: DRV8662EVM Downloaded the DRV8662EVM Source Code (sloc285.zip) file from the DRV8662EVM product page, and it expanded to a DRV8662EVM_RevD folder. Looks like the code is configured for the IAR MSP430 IDE, not CCS. Anybody…
