    Hi Ethan, In the case of input protection, the clamping diodes can be placed at the input of the ADC, not necessarily the OPA input. I recommend the following video as well, which goes over many options to protect the inputs of the ADC. The ADS8661, ADS8665…

    Hi Luke, Both ADS8661 and ADS8681 definitely should work for analog DC input or 1KHz sinewave signal. The glitch you observed was caused by something else in your system. When you check glitch on the analog input, make sure you have proper settings on…

    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…

    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…
