Re: AD9915 SDIO response time problem
Hi Hasan, The fastest rate that the internal state of the device(AD9915) transitions, is the rate reflected at the SYNC_CLK output. This rate is around 156 MHz which is greater than 80 MHz. However,...

Hi Dhingra, The formula can be found on page 22 of the datasheet which is: Ramp Rate = (N + 1) × System Clock PeriodGiven this, you can derive this equation.Ramp Interval = |Fupper - Flower| x (N + 1)...

Hi Alex, From your data, I do not think the calibration is done well. There is a negative offset. If you remove the offset, the accuracy will be better. See attached the data I have.
View ArticleRe: ADA4091-2
Hi W Choo, You can check page 14 of the datasheet on the output stage of the ADA4091-2. With your outputs saturated, you would expect your output voltage to be within 50mV of the rail. So I would say...
View ArticleRe: ADE7878 RMS Voltage measurement
Hi Dlath, It was my mistake. I gave an external resistor divider and then kept JP7A open (I am only measuring phase A voltage right now). So in effect, there were two resistor dividers and the 200mV...

Hi Luca,following your suggestion I've re-installed ADIsimPE and now everything works fine!!Probably something gone wrong during the update.Thanks a lot !!Ciao
View ArticleRe: Can I leave open unused analog input channel on AD7682?
Hi Sofy, Since you will not be using the 2 analog input channels of the ADC, it's a good practice to tie the analog inputs to a known state. In your case, connecting it to GND. Regards,May

Yep, correct voltages on all the pins - +5V on VDD, no analog pin can exceed that as they are all derived from the same power rail; maximum of 2.5V on the logic inputs from a 3.3V rail that's derived...
