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.

Slew rate (V/s)

Required number input.

Peak voltage (V)

Required number input.

Compute the maximum full-amplitude sine frequency as slew rate / (2 x PI x peak 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]

Max frequency (Hz)

The resulting max frequency 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.

• Ideal ADC SNR

  Estimate ideal full-scale sine-wave signal-to-quantization-noise ratio as 6.02N+1.76 dB. Oversampling, thermal noise, distortion, and reduced input amplitude are not included.

• Equalizer Boost Db

  Convert an equalizer's high-frequency-to-reference voltage gain ratio to decibels; both gains must use the same amplitude convention.

• ESR Limit For Ripple

  Compute the maximum output capacitor ESR in milliohms that keeps ripple-induced ripple voltage within budget as ripple millivolts over ripple amperes.
