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.

Sensor Charge (C) (C)

Required number input.

Feedback Capacitance (F) (F)

Required number input.

Calculate ideal inverting charge-amplifier output voltage as −Q/Cfeedback for a piezoelectric sensor; leakage and reset circuitry are excluded. 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.

• Piezoelectric charge, voltage, displacement, sensitivity, and resonance depend on material constants, axis, geometry, preload, boundary conditions, frequency, temperature, dielectric loss, amplifier input, and hysteresis. Static measurements are limited by leakage.
• 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.

• Piezoelectric Open-Circuit Voltage

  Estimate open-circuit piezoelectric voltage as generated charge divided by effective capacitance. Loading, leakage, and amplifier input impedance can reduce measured voltage.

• Voltage Sensor Divider Ratio

  Calculate the unloaded resistive voltage-divider ratio Rbottom/(Rtop+Rbottom); loading and resistor tolerance are excluded.

• ADC Quantization Error Bound

  Calculate the ideal rounding quantizer's maximum absolute error as half an ADC LSB. Assumes a uniform quantizer and input within the conversion range; offset, gain, and noise errors are excluded.
