Hi Michael Soldierram, The RTD input looks fine. You might need to change the component values in the filter, but that can be done experimentally once you get your prototypes since those...

Hi. Wow that was fast. My hardware engineer looked at the graphs and agreed with you that the clock edge seems to be out of phase. I can reverse the polarity of the clock easily in the Xilinx SPI bus...
View ArticleForum Post: RE: ADS1261: Weird response for few ICs in a batch order.
Hi Takuchi, You should be able to power up the ADC, pull the START pin high, and see DRDY toggling at ~50 Hz ( the default data rate) without doing anything else. That is the simplest test you can...
View ArticleForum Post: RE: ADS8598H: ADS8598H isolated interface to microcontroller
Hi Andrea and Sara, I see by the note in your schematic that you have considered tying the /CS input low. You could perhaps then use the ISO7762 - bring one CONVST over (for both A and B) and the SCLK...

HI peimin Wu, The compliance voltage will scale across AVDD. So at ~700mV of IDAC voltage compliance, with a 250uA IDAC, you are still >0.99 normalized IDAC current (according to Figure 10 on the...

Hi Kanava, Unused AIN/GPIO pins should be grounded to reduce noise pickup, as Collin mentions in the thread you included. Regards, Joel

Tom, I figured out i'd rather have control over /CS than over FRSTDATA, which in fact feels redundant in my application. If I remember correctly, by controlling /CS we can choose whether to read the...

Hi Jonjan, Thanks for your information. You mentioned the CH3 is used to measure the supercap voltage, but none of the signals in these circuit are connected to the ADC's input (A3_P and A3_N), so it...

Hello Lhagva, There is an error in the ADS1285EVM User's Guide. You need to change the AVDD2 supply voltage, not AVDD1. AVDD1 is referenced to AVSS; changing AVSS from GND (0V) to -2.5V by moving J4...
