(1) Ratio of output level with 1kHz full-scale sine-wave input, to the output level with the AC signal input shorted to ground, measured A-weighted over a 20Hz to 20kHz bandwidth using an audio analyzer.
(2) All performance measurements done with 20kHz low-pass filter and, where noted, an A-weighted filter. Failure to use such a filter can 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, can affect dynamic specification values.
(3) ADC_CHx_FULLSCALE_VAL = 1'b1 and 10kΩ input impedance for High Swing Mode
(4) ADC_CHx_BW_MODE = 1'b1 and 40kΩ input impedance for Wideband Mode
(5) PWR_TUNE_CFG0 = 0xD4, PWR_TUNE_CFG1 = 0x86 and PLL_DIS = 1'b1 for Power Tune Mode
