ADC Resolution: Bits vs Discrete Levels

How an analog-to-digital converter's resolution (in bits) maps to the number of discrete quantization levels (2^N), with typical uses.

Resolution (bits)Discrete levels (2^N)Typical use
8-bit256Consumer, displays
10-bit1,024General control
12-bit4,096Sensing, data acquisition
14-bit16,384Precision measurement
16-bit65,536Audio, precision instruments
24-bit16,777,216High-end audio, metrology

Method & sources

Levels = 2^(bits), a mathematical definition. Typical uses are common industry practice, not strict rules.
