(1) Ratio of output level with 1-kHz full-scale sine-wave input, to the output level with no signal, 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. The low-pass filter removes out-of-band noise, which, although not audible, may affect dynamic specification values.
(3) The device performance parameters, SNR, DR and THD+N, are mainly limited by single-bit PDM modulator generated data output. The THD+N peformance for single-bit PDM modulator output itself is generally not so good for signal above –10-dB full-scale. The datasheet measured numbers are with using audio equipments consist of high performance PDM modulator output generator.
