  • RE: ADS8861: Direct compatibility between LMH32401 and ADS8861

    Hello Andrianirina, Since you are using less than 1/4 of the full scale input range of the ADS8861 (6.6Vpp full scale input), with the output of LMH32401 limited to 1.5Vpp, you have multiple options on where to set VOCM and VOD. In any case, if you…

  • RE: CCS/ADS8861: Interfacing ADS8861 with TMS320F28379D

    Kiran, Not sure what you mean whether SPISTE can be triggered as pulse. SPISTE pin will stay low whenever SPI is transferring (or) receiving data. Once the transaction is complete, SPISTE signal goes high. So, it shouldn't have any problems interfacing…
