H7 ADC revisited (Bandpass sampling and analog bandwidth of the 16-bit ADC peripheral of the STM32H7, Part IV)

Posted onApril 17, 2022April 17, 20222 Comments

The question that interested me was: How strongly does the SNR of the ADC-peripheral of the H7 depend on the chosen clock source? Unfortunately, neither the H7 datasheets nor application notes like AN5354 treat this topic. The FFT plot shown in figure 1 of AN5354 Read More …

H7 ADC revisited (Bandpass sampling and analog bandwidth of the 16-bit ADC peripheral of the STM32H7, Part III)

Summary: It is shown that the shape of the transfer function and of the SNR of the internal ADC of the STM32H7 vs. frequency of the applied signal can be explained with a very simple simulation model up to quite high signal frequencies. The PLL Read More …
