IWR6843: MHz vs Msps for ADC

Jiefei Xia

Part Number: IWR6843

Hi,

Our official vital signs monitoring instruction says "the maximum sampling frequency of the ADC in the IWR6843 is 25 MHz". The IWR6843 data sheet says its ADC sampling rate is 250,000 ksps (250Msps).

By my understanding, 1MHz should have the same meaning as 1Msps. Is it a typo on the instruction?

Hi Jiafei,

I see this in the datasheet. 25 MHz should be right.

Hi Jiefei,

Thank you for finding this. I'm very confident it's a typo. I would refer to the datasheet value as the gold standard.

Best,

Nate
