Use this electronics calculation for a first-pass component, converter, signal, motor, or sensor estimate when the stated operating conditions and units match the device data.

Switching (V) (V)

Required number input.

Reference (V) (V)

Required number input.

Measure signed comparator input offset as the observed switching input voltage minus the nominal reference voltage. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Input Offset (V) (V)

The resulting input offset (v) returned as a number.

• Comparator thresholds and hysteresis depend on topology, resistor tolerances, input common-mode range, offset, bias current, output stage, supply, noise, and propagation delay. Confirm that every state stays within datasheet limits.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Check the result against the current datasheet and worst-case operating corners, then verify the circuit or measurement with simulation and bench testing where failure matters.

• Differential Input Voltage

  Compute the signed differential input voltage as V+ minus V-.

• Offset Drift

  Compute the signed input offset voltage drift as delta Voffset(uV) / delta T(degC); the temperature interval must not be zero.

• ADC LSB Voltage

  Calculate one ideal ADC code width as full-scale input span divided by 2^N. Full-scale span is the high-to-low range, not necessarily the reference voltage for every ADC topology.
