View ArticleForum Post: RE: Noise issue in a voltage measurement APP with the ADS1247
Hi Jason,Yes, there is a noise penalty for single-cycle settling. Between the ADS1232 and the ADS1247 the digital filters are much different. The ADS1247 uses a coefficient based FIR filter whereas...

Hi Shashank,Welcome to the TI E2E forums.The ADS1259 can measure differential voltages as large as +/-Vref. However, the input voltage range is also limited by the ADS1259 supply rails. Are you...
View ArticleForum Post: RE: ADS1234 Data rate problem
Hi Jignesh,I think the best thing to do at this point is to replace R5 and R6 (4.7k resistors) with 0 ohm (direct short). There should be a low impedance connection between the AGND and DGND of the...
View ArticleForum Post: RE: LMP91000 voltage sweep
Hi Jonathan,If you apply different Vref to the LMP91000, the main impact is in the working point of the TIA (its internal Zero).Consider that the min Vref you can apply is 1.5V, while the max is the...
