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.

Sensitivity (dBV/Pa)

Sensitivity in decibels relative to 1 V/Pa.

Convert microphone sensitivity from dBV per pascal to millivolts per pascal as mvPerPa = 10^(sensitivityDbV / 20) * 1000, referenced to 1 V/Pa. 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]

Sensitivity (mV/Pa)

Output voltage per pascal of acoustic pressure.

• Microphone sensitivity, SPL limit, directivity, and phantom-power calculations depend on frequency, load, reference pressure, weighting, polar pattern, preamplifier noise, distortion criterion, supply circuit, and acoustic environment.
• 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.

• Load Cell Output Voltage

  Estimate load-cell voltage from excitation voltage, full-scale sensitivity in millivolts per volt, and fraction of rated load; linear response is assumed.

• Microphone Max Spl

  Maximum SPL from the microphone's maximum undistorted RMS sound pressure, referenced to 20 µPa.

• Op-Amp PSRR dB to Linear

  Convert power-supply rejection ratio from voltage-ratio decibels to a linear rejection factor, 10^(PSRR/20). A 80 dB PSRR means a 10,000:1 small-signal voltage rejection at the stated frequency.
