ad7277 analog input 'hold time'

Good morning,

I want to use the ad7277 to digitize the output of an analog current integrator.  For simplicity, I want to use the CS (chip select) input of the ADC also to reset the current integrator output to zero (by discharging the capacitor with an analog switch).

In this case, the input voltage of the ADC would start changing almost immediately after the CS signal has gone low.

Is there any 'hold'-time requirement for the analog input that would be violated in this case, or is this a valid operating mode?

Thanks and best regards,
