Part Number: ADS9810 Other Parts Discussed in Thread: ADS9803 , , ADS9811 , ADS9813 Hi TI Team,
We want to use a digitally adjustable input SAR ADC in the data acquisition system to read the data from the PZT sensor. Below is the high-level block diagram…
Part Number: ADS8354 Other Parts Discussed in Thread: ADS9810 , ADS9811 recommend a ti adc
SPI control, 4-channel input or more, with an internal PGA being the best, SARADC, sampling rate 1M or more, simultaneous sampling of all channels.
Hi Youwei ,
All SAR ADCs where the sampling capacitor is exposed to the input pins will experience some charge kick-back like this. The inputs must be properly driven using a drive circuit to avoid such a kickback. Some resources regarding this:
…
Hi Rick,
Thanks for your post! Out of curiosity, do you need the full 8MSPS/CH sampling speed to measure your load cells? Are you only measuring two voltage signals? We do have a slower, higher channel count ADC: ADS9813 - 18-bit, 8CH, 2MSPS/CH ADC…
Part Number: PGA855 Other Parts Discussed in Thread: INA851 , ADS9810
Hello,
I am designing a circuit in which a differential input signal is amplified with the INA851 and the PGA855 and then digitized with the ADS981X A/D converter. The amplifiers…
