adc quantization step calculator online

Use adc quantization step calculator online for reference V, bits. Ideal unipolar full-scale span divided into 2^N bins. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.

How to use it

Enter reference V. Set bits. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
reference VMain input. Positive values. 3.3
bitsOption. Whole numbers. 12

Calculation method

lsb_V = reference_V/2^integer(bits,1,32); half_lsb_V = reference_V/2^(bits+1) (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply adc quantization step calculator to the case below, keeping the displayed units and assumptions. Ideal unipolar full-scale span divided into 2^N bins.

Calculated result for these inputs:

Output:

  "lsb_V": 0.0008056640625,
  "half_lsb_V": 0.00040283203125
}

Choose the right tool

Match the topology before entering values: series and parallel networks, inverting and noninverting stages, and buck and boost converters use different equations. Component ratings, parasitics, protection and measured conditions require separate review.

Limitations and common mistakes

  • Ideal unipolar full-scale span divided into 2^N bins. Ideal nominal component model. Verify topology, operating range, tolerances and ratings against the actual component datasheet.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
