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.

Zero Current (V) (V)

Required number input.

Sensitivity (V/A) (V/A)

Required number input.

Current (A) (A)

Required number input.

Calculate linear current-sensor output voltage from zero-current offset, volts-per-ampere sensitivity, and signed current. 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]

Output (V) (V)

The resulting output (v) returned as a number.

• Compact electronics formulas omit some combination of tolerances, temperature drift, bandwidth, loading, parasitics, noise spectrum, nonlinearity, clipping, calibration, layout, and device-specific limits. Typical datasheet values are not guaranteed 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.

• Accelerometer Voltage Output

  Calculate linear analog accelerometer voltage from zero-g voltage, sensitivity in volts per g, and signed acceleration in g.

• Gyroscope Voltage Output

  Calculate linear analog gyroscope voltage from zero-rate voltage, sensitivity in volts per degree per second, and signed angular rate.

• LVDT Output Voltage

  Calculate linear-region LVDT output voltage from calibrated sensitivity in volts per millimeter and signed core displacement; excitation and demodulation are assumed fixed.
