(1) Ratio of output level with 1-kHz, full-scale, sine-wave input, to the output level with the inputs short-circuited, measured A-weighted over a 20-Hz to 20-kHz bandwidth using an audio analyzer.

(2) All performance measurements done with 20-kHz, low-pass filter and, where noted, A-weighted filter. Failure to use such a filter may result in higher THD and lower SNR and dynamic range readings than shown in the Electrical Characteristics table. The low-pass filter removes out-of-band noise that, although not audible, may affect dynamic specification values.

(3) When IOVDD < 1.6 V, the minimum V_IH is 1.1 V.
