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.

Feedback R (Ω)

Required number input.

Input R (Ω)

Required number input.

Output swing (V)

Required number input.

Compute comparator hysteresis from the output swing and the positive-feedback divider: width = output swing x Rreference / (Rfeedback + Rreference). 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]

Hysteresis width (V)

The resulting hysteresis width 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.

• Comparator Hysteresis Band

  Comparator hysteresis-band width between upper and lower switching thresholds.

• Current Shunt Amplifier Gain

  Voltage gain of a current-shunt amplifier from output swing and measured shunt input swing.

• Magnetoresistive Sensor Output

  Change in divider output voltage when the upper magnetoresistive element changes by ΔR while an equal fixed resistor remains below it.
