  • RE: OPA378: circuits and amplifier as a reference buffer

    Resolved
    Hi Frank, why not taking multiple REF3125, one for each four channels? Also, the output decoupling capacitance of REF3125 should be adapted to the needs of PWM circuit. Why not adding a suited output filter to the REF3125? Kai

  • RE: ADS1258: How to use PGA281 with ADS1258?

    Hi Poh, Thanks for providing these additional details. Given your configuration, the PGA281 should work in your system. Please note that the input range of the PGA281 extends beyond the input range of the ADS1258 MUX. Therefore, as long as you are…

  • RE: REF3025: Reverse current on output for REF30XX

    Hi BR, I can help you with this request. What are the sizes on R1 and R2? The REF3025 cannot sink current and maintain proper regulation. I would recommended a REF3125 or REF3325 which are P2P which can sink current.
