How fast resolution could I get using 12 bit ADC?

Hello everyone,

 

How fast could I get the ADC conversion time from 1800 sensor using 60 GPIO pins and 30 ADC pins?

 

I am sensing analog signal from 1800 points using 12bit ADC in MK60DN512ZVLQ10 Microcontroller.

It takes little over 170ms now, but from the datasheet Min 20 Ksps(1800 / 20 K = 90ms) ~ Max 818.330 Ksps(1800 / 818.330 K = 2.2ms).

I am using MQX too.

I need 5 ms resolution. Is is possible to get the result with MK60DN512ZVLQ10?

 

If not, do you have other microcontroller to get this resolution?
