With timer trigger, the sampling rate cannot reach 1msps

Ok, so don't use the TIM, and let the ADC saturate in continuous mode.

Pretty sure with the correct Prescaler/Period the TIM could clock generate an update at 1 MHz

Single channel, 12-bit is supposed to hit 1.5Msps, triple interleave 4.5Msps

​Thank you for your reply

Pretty sure this is not correct.

But as Clive suggested, you can go with the full speed in continuos mode. This would still produce equidistant results.

Keep the requirements of the input amplifier stage at that sampling rate in mind.
