(1)

Ratio of output level with 1-kHz full-scale sine-wave input, to the output level with the AC signal input shorted to ground, 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)

For best distortion performance, use input AC-coupling capacitors with low-voltage-coefficient.
