Helpful information - thanks Frank!

Hi, In the interest of reducing noise, is it of any benefit to use a separate regulator for AVDD (isolating it from DVDD's regulator)? If so, should REFP be referenced to the same source as AVDD, or should it be referenced to DVDD? Additionally, is there a specific 3V3 regulator that should be used?...

Thanks slacker,

I think you're write - I ended up coding a single pole HP filter from the ground up, and it seems to be doing the trick. Thanks for the help!

Hey folks, I'm trying to implement a high pass filter, where the cutoff frequency is controlled via a scaled pot input. This is what I'm trying, but it's giving me a low pass filter instead. ( ? ) equ hp0 reg5 ;register for high-pass filter equ khp reg14 ;register for cutoff frequency ;load and scal...

Hi, I'm trying to use the cho rda command to read from a point in memory, but I'd like to use a pot to control which point from memory the sin/cos oscillates about. How should I implement this? This is the general idea of what I'm trying to do: ldax pot0 wrax addr_ptr, 0 cho rda, sin0, %0, addr_ptr*...
