  • RE: ADS8506: Differences between ADS8506IB and ADS8506I

    Hello Takashi, Your understanding is correct, ADS8506IB has smaller INL,DNL and Full Sclae Error. The new SAR ADCs which can cover +/-10V bipolar and unipolar input include ADS8661 (12-Bit, 1.25mSPS), ADS8665 (12-Bit, 500ksps), also 14-Bit ADS867x and 16…

  • RE: ADS8506: VANA Cap

    Resolved
    Hi Takashi, 1. I did not see any risk to use a ceramic cap for the power supply, ceramic caps are frequently used on our EVM boards. 2. The analog power supply is very important for data conversion because it can directly affect your measured performance…

  • RE: ADC with +/-5V analog input rage with parallel interface

    Resolved
    Hi Tom, We have input which can vary from -5V to +5V, let me check in our circuit on what could be the possible changes if we go with attenuation. Meanwhile may i know how long ADS8661 will be in market,i mean to become obsolete. Thanks and Regards …
