Calculation steps
Work through one step at a time or reveal the complete calculation. The steps use your current inputs.
How to calculate
Use both entered endpoint boundaries to remove span and offset before examining every interior transition.
Endpoint LSB=(last−first)/bin count; DNL=width/LSB−1; INL=(boundary−first)/LSB−index
Worked example
Boundaries0,1,2.1,3,4 give DNL0,+.1,−.1,0 LSB and interior INL0,+.1,0.
Assumptions and input details
Entered contiguous range only, not necessarily the full converter. Nondecreasing boundaries allow zero-width missing bins. Endpoint-fit convention differs from best-fit INL and does not include measurement uncertainty or ADC compliance testing.

Using this calculator
Can I enter my own problem?
Yes. Replace the example values with your own inputs. The result, calculation steps, tables and applicable diagrams update from those inputs. Blank or invalid values clear the result; example values are never silently substituted for missing inputs.
Are the results exact?
Results use floating-point arithmetic and displayed rounding. Read the formula, assumptions and any stated data precision before interpreting the result.
Is my input uploaded?
The calculation runs in your browser. No account, file upload or external AI service is required. Inputs are not saved between page reloads.
Map voltage to an ideal equal-bin ADC code or inspect the voltage bin represented by an entered code.
Estimate the sine-wave SNR ceiling from independent RMS aperture and clock jitter, with a stated ENOB equivalent.
Fit y=a+bx to 2–100 entered coordinate pairs. Inspect the regression equation, correlation, R², predictions, residuals and a scatter plot.
