MSP Friends & Family,
Our customer is asking the following:
We are using the ADC in the MCU for sampling at 20 Hz rate and the input bandwidth is 8 Hz. If the input is a clean, DC level (1.67 V) what is the expected noise? Will the output be a single ADC level or will it vary about a mean ADC level by many ADC counts? If so, by how much variation? The Reference voltage is 3.3V from a battery. FYI I am not interested in the gain or linearity – they’re in the data sheet already.
Comments welcomed.
TY,
CY
