STM32F373CCT6 2 Channels Single ended wired together for 16 bit ADC interleaved 50 KHz to 100 KHz , Can it be done with 2 Differential channels at same speed 50KHz to 100KHz or is it stuck at 16Khz max speed in differential mode

Device STM32F373CCT648 pin We currently using 2 single ended 16 bit SADC inputs one on SADC1 PE9 and one on SADC2 PB2.We interleave the two 50KHz single channels using a 10uS delay between them. This uses DMA SADC transfer an interleaves the signal t...
