Re: ADE7880 Neutral - Ground Question
Hi Dave, Yes I was referring to the AGND and DGND which is connected to the host microcontroller GND. Due to this, the entire board was spoilt when I mistakenly connected the phase to the neutral. So I...

View ArticleRe: AD9910 - Simultaneous use of RAM and DRG- Is it applicable?
Hi Freddy, Louijie is correct. The AD9910 DRG and RAM use the same registers inside the part so only one can be functioning at a given time. However, the AD9910 has a second ramp generator exclusive...
View ArticleRe: AD9910 - Simultaneous use of RAM and DRG- Is it applicable?
Hi Freddy, Some ADI colleagues pointed out that I made a mistake. I was thinking of the Single Tone Profiles instead of the DRG, and those cannot be used in conjunction with the RAM because they use...
