Is ADC driver (op-amp based) is needed for measuring over cable with STM32 ADC?

Hello ST team,I am designing a hardware with STM32G4 family. I want to measure a differential signal by MCU's ADCs over a cable of 50 cm. Is it needed to use op-amp as ADC driver or I can connect it to the MCU pins directly?

Should i use single transfer mode instead of double buffer mode in DMA for my program?

Hello everyone,Actually I am making a data acquisition system in which my mcu takes analog data from a sensor and stores it in a buffer, and then into a 2nd buffer with the help of DMA in double buffer mode. Now i want to transfer this data via UART
