¹POR is % of reading.

²Nonlinearity is defined as the maximum deviation (in percent error) from a straight line connecting the readings at 0 V and at 200 mV rms.

³After fourth-order error correction using the equation

y = − 0.31009x⁴− 0.21692x³− 0.06939x²+ 0.99756x + 11.1 × 10⁻⁶

where y is the corrected result and x is the device output between 0.01 V and 0.3 V.

⁴Crest factor error is specified as the additional error resulting from the specific crest factor, using a 200 mV rms signal as a reference. The crest factor is defined as

V_PEAK/V rms.

⁵DC offset does not limit ac resolution.

⁶Value is measured with respect to COM.
