Thank you for interest in the Intel® Curie™ Boards.
I found the following information in the Intel® Curie™ Module – Datasheet (http://www.intel.com/content/dam/support/us/en/documents/boardsandkits/curie/intel-curie-module-datasheet.pdf):
3.2.17 Analog-to-digital converter (ADC) unit
- 2.24 MSPS conversion rate – See the Intel® Quark™ SE Microcontroller C1000 Datasheet for more details.
“… lower bit resolution can be sampled faster than the 12-bit maximum.”
MSPS stands for Mega samples per second.
That means that the max rate of sampling for 12-bit resolution is 2.24 mega samples per second.
Please let me know if you find the previous information useful.
If you need further assistance, don’t hesitate to contact us.
Thanks for our reply.
The datasheet says “… lower bit resolution can be sampled faster than the 12-bit maximum.”
and the curie module seems to support 12, 10, 8 and 6 bit resolution.
So I am wondering if it implies that 2.24 MSPS is for 6bit and it keeps dropping as the number of bits of resolution increases.
So I was thinking if the samples / sec would be lower for 12bit than for 6bit.

I’m sorry for the confusion, lower bit resolution (10-bit, 8-bit, and 6-bit) can be sampled faster than the 12-bit maximum (which is 2.24 MSPS).
It implies that 2.24 MSPS is for 12-bit and it keeps getting higher as the number of bits of resolution decreases.
The samples per second are indeed lower for 12-bit than for 6-bit. That is because it takes less time to sample data that is “smaller” (bit wise). For more information on sampling, please check the following link http://control.ucsd.edu/mauricio/courses/mae143a/lectures/8sampling.pdf.
The maximum sampling rate for the 12-bit resolution is 2.24 Mega samples per second.
The sampling rate is greater than 2.24 MSPS for the remaining resolutions (10-bit, 8-bit, and 6-bit).
I hope that helps you obtain a better understanding of the ADC in the Curie module
Thanks Andres, that really helps!!
