The low bandwidth, high resolution ADCs have a resolu- tion of 16 bits or 24 bits. However, the effective number of bits of a device is limited by noise.This varies depend- ing on the output word rate and the gain setting used. This parameter is specified by some companies as effec- tive resolution. Analog Devices specifies peak-to-peak resolution, which is the number of flicker-free bits and is calculated differently from effective resolution. This application note distinguishes between peak-to-peak resolution and effective resolution.
