Dear Expert,

I use the ADC3101 designed a PCB for vibration data acquisition, but

  1. I found the signal had a serious DC bias,do you have any idea how to remove it through the setting of the dsp register? 
  2. and also , the noise is very high. do you have any suggestion? 6064.base_main_Rate22_pps_driver.h
  3. in addition, I use the splitter function block to copy signal into two Left and right channel to do different processing, and in the right channel, I use Abs function, but not all of  the signal turn to positive . could you kindly help to check my setting of my resigter.

    Hello,

    Our ADC3101 mini-DSP expert is out until next week.  I will loop him in to comment when he's back.  

    Have you considered the TLV320ADC5140 or TLV320ADC6140?  It's an easier to use device with much improved performance and sampling rates which are often required in vibration analysis.
