(3)

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.

(4)

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.

(5)

Unless otherwise noted, all measurements use output common-mode voltage setting of 1.35V, 0-dB

output level control gain, 16-ohm single-ended load.

(6)

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.
