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.

Offset change (µV)

Required number input.

Temperature change (°C)

Required number input.

Compute the signed input offset voltage drift as delta Voffset(uV) / delta T(degC); the temperature interval must not be zero. 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]

Offset drift (µV/°C)

The resulting offset drift 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.

• Op-Amp Open-Loop Gain

  Calculate open-loop voltage gain A=Vout/(V+−V−) from an unsaturated operating-point measurement. Differential input cannot be zero; this scalar does not capture frequency-dependent gain.

• Chopper Amplifier Offset

  Input-referred residual DC offset of a chopper amplifier from its zero-input output offset and closed-loop voltage gain.

• CMRR Linear

  Compute the linear common-mode rejection ratio as Adiff / Acm; the common-mode gain must not be zero.
