FAQ
Can each channel of ADCs in the NuMicro® family microcontrollers with the same module be sampled simultaneously? Issue Date：2017-02-02
No, simultaneous sampling of multiple channels are not supported by ADCs with the same module. However, the NuMicro® M0519 series supports two ADC modules that can simultaneously sample channels from different modules.
For example, in the NuMicro® M451 series:
When AVDD works at 4.5V - 5.5V, the maximum ADC clock frequency is up to 20 MHz, and it needs 20 ADC clocks to complete an A/D conversion.
Thus, the minimum sampling frequency interval for each channel of the ADC is 1 uS.
