    Thanks for the comment. I need to get 0.1mg resolution data (@ 1000samples/sec) from an accelerometer for my project. Since I couldn't find any accelerometers with ranges smaller than +/- 1g, I need...

    so I tried single-ended mode like you said above (but without a reference voltage source; I'm using a standard 3.3V regulator for AREF). I'm still getting noise (using all the capacitors and AGND...

    BTW, I absolutely don't mind ditching Arduino IDE if I have to (to access the differential pins). I might still be a noob in plain 'ole C, but I'm willing to try (and my experience in other languages...

    I'm sorry for the late reply. I had some issues with the data being sent from the T3 to the PC (through USB Serial), and so I spent a lot of time trying to debug it and fix it.

    Basically, whenever...

    thanks again for the massive amount of knowledge passed down. I will try to respond point by point.

    - I tried bypassing the internal regulator in the T3 (using 3.3V reg), and I kept...

    @Constantin

    I just realized that I never knew the impedance value of the signal. It turns out it's around 32kHz, but I have no idea what that means (is it too high in this case?)

    But, first,...

    I wanted to thank you for taking the time to reply. :D

    I ran it off 3 AA batteries (4.5V) regulated to 3.3V (by a typical LD33V fixed regulator). However, I connected that through the VIN pin (had...

    Just an update (to help others):

    I tried the ADC of the Teensy3, and I noticed it had a TON of noise on it (practically not even close to 16-bit. Maybe even 13 or 12). It was THAT bad. So, I...

    thanks for the information.

    The Teensy probably won't be doing a lot of stuff (only reading ADC and sending through USB), but I guess there is no way to find out how much noise there will be...

    My bad for asking an RTFM-worthy question; I just checked the website and realized the Teensy 3.0 has a 3.3V regulator. Also (obviously), its I/O pins operate at 3.3V

    @Nantonos

    I previously looked into dedicated ADC chips (similar to the ADS1115), but the low sampling rate makes it unusable for my application. I haven't had much luck finding a dedicated ADC...

    Great post! Certainly helpful!

    I realistically only need about 2k samples per second, so I'm probably not going to write my own code :D

    Teensy 3.0 ADC details

    hey everyone,

    I'm new to this microcontroller programming stuff, so bear with me.

    I just need to double check that I have the details about the ADC correct here:

    The Teensy 3.0 has the...
