2.3.1.3 Microphone Bias
PARAMETER TEST CONDITIONS MIN TYP MAX UNIT
Bias voltage 3/4 AVDD − 100 m 3/4 AVDD 3/4 AVDD + 100 m V
Bias-current source 3 mA
Output noise voltage 1 kHz to 20 kHz 25 nV/√Hz

NOTES: 3. Ratio of output level with 1-kHz full-scale input, to the output level with the input 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
results 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. Ratio of output level with 1-kHz full-scale input, to the output level with all zeros into the digital input, measured A-weighted over
a 20-Hz to 20-kHz bandwidth.
