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…
Part Number: ADS8665 Other Parts Discussed in Thread: ADS8661 , ADS8556 , ADS8557 , ADS8558 , ADS8568 , ADS8548 , ADS8528 , THS4561 , OPA192 Hi 2 all! Maybe my question is fool byt i need answer. I looking for ADC for sampling 50kHz bipolar signal. My choise is…
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…
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 …
