Right, an 8 bit ADC gives you 2^8 discrete voltage levels as input, so 256 possible values. An 12 bit ADC has 2^12, or 4096 possible input levels- giving much finer granularity between each level "bin", thus increased dynamic range. There's other techniques as well such as adding dither, oversampling, etc. to increase your dynamic range at the cost of something else- usually bandwidth, computing power, bit resolution, or all of above.
