Doubts about ADC differential mode in STM32L41x up to STM32L46x

Uwe Bonnes
Principal III

Hello,

both datasheets and rm0394 rev 4 talk about "­ Manage single-ended or differential inputs" and Figure 39. : ADC block diagram show ADC_INP[16:1] and ADC_INN[16:1] . However Pinout tables in chapter 4 : Pinouts and pin description only shows ADC1_INx. Either the documents misses a mapping from ADC1_INx to ADC_INPx and ADC_INNx or differential inputs are not available at all on L41-L46.

Please clarify! Thanks!
