Re: AD7195 conversion question
Hi PeterVers,Linked here are the FAQs for the AD719x. The last page gives some information on the analog input to digital output relationship. Data = [(0.75 × VIN × PGA_Gain/VREF) × (223) – (Offset_Reg...

We are applying 3.3VDC to VPS, which gives about 3.2VDC so VPI and VPSD. After using a spectrum analyzer, we are able to see an output signal from the board. Our problem is now that we are not seeing...

You need to use the BUFIO/BUFR on the clock, and all the rest FCO, DATA lines on the same bank.This allows you to use the SERDES with maximum IO bandwidth on these devices.At the output of the SERDES,...

It's strange that when you reduced the voltage of Vdrive, SDO didn't reduce. Could you try disconnecting Vdrive completely and measure the voltage on SDO?
View ArticleRe: ADRF6518-EVALZ Board Software Issue
Hi Bill, You must apply more than the DC supply voltage to get the desired gain of the ADRF6518. You must also apply DC voltages to the analog gain pins: VGN1, VGN2 and VGN3. Else those pins will...

Yes this is correct. There was originally a capacitor located there that was later replaced with the 0 ohm resistor that is currently listed in the BOM. Since it was just a BOM change the reference...

Re: ADUM3223 H-Bridge Turn off issue
Thanks for the schematic. It looks like it is properly set up. You don't need the 1 Ω resistor from the MOSFET sources to the GNDA/B pins, but it shouldn't be the source of the issue. The output...
