At 225k samples per second with 12-bit resolution, this part sits in the mid-speed precision band. It is fast enough for multi-channel sensor scanning, audio-band processing, or motor-current monitoring, but not built for RF or video-rate capture. The 16-channel mux means you can route several analog signals through one converter, saving board space and cost compared to a per-channel ADC array.
