How to find package specific specfications? STM32H723ZG for ADC

So i was looking at the 16-bit ADC characterisics in the datasheet of STM32H723ZG.

Here it says for LQFP packages, values might differ. I have LQFP 144 , and i can't find any package specific datasheets. Where can i find the information for my package.

I was trying to find the maximum adc sampling rate.

    Hello,

    I don't think these parameters are available for each package but I invite you to refer to the application note: AN5354 "Getting started with the STM32H7 Series MCU 16-bit ADC"

      So according to this , maximum adc clock frequency is 12MHz.
