LTC2983 20ch Type-T Thermocouple maximum scan rate

Hello,

I would like to use LTC2983 or 2984 for Type T thermocouple measurements.
10 sensors (full usage of 20ch and no capacitor filtering at inputs).
Also only 2 conversion method, no need for open wire detection. 

What is the fastest rate I could scan all channels?

No additional delays against mux settling time needed.
