(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+N and lower SNR and dynamic range readings than shown in the Electrical Characteristics. The low-pass filter removes out-of-band noise, which, although not audible, may affect dynamic specification values.
(3) Unless otherwise noted, all measurements use output common-mode voltage setting of 1.35 V, 0-dB output level control gain, 16-Ω single-ended load.
(4) Ratio of output level with a 1-kHz full-scale input, to the output level playing an all-zero signal, measured A-weighted over a 20-Hz to 20-kHz bandwidth.
(5) When IOVDD < 1.6 V, minimum VIH is 1.1 V.
(6) Additional power is consumed when the PLL is powered.
