I plan on interfacing a Sparkfun MUX Breakout (CD74HC4067) with a Sparkfun Artemis Module
MUX: https://www.sparkfun.com/products/9056
DATASHEET: https://www.sparkfun.com/datasheets/IC/cd74hc4067.pdf
I need to swap between ten channels, 120 times a second. In total, there would be 1200 mux channel swaps per second. Can the ADC of the Artemis handle this? And if not, what would be the best option to make this possible? Would a op-amp suffice?

Yep; check out the datasheet https://cdn.sparkfun.com/assets/1/5/c/6 ... 0_15_0.pdf (page 749 has the analog mux ADC info) looks like it can do 12 analog channels @ 1.2MS/s with 14-bit precision
