Note:
Permanent device damage may occur if the above Absolute Maximum Ratings are exceeded. Functional operation
should be restricted to the conditions as specified in the operational sections of this data sheet. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

Notes:
1.
DR = VIN + 20 log (RMS signal/RMS noise). Measurement bandwidth is 300 to 3400 Hz. Valid sample rate ranges
between 4000 and 12000 Hz.
2.
0 dB setting for analog and digital attenuation/gain.
3.
THD = 20 log (RMS distortion/RMS signal). Valid sample rate ranges between 4000 and 12000 Hz.
4.
At 0 dB gain setting, 1 Vrms input corresponds to –1.5 dB of full scale digital output code.
5.
These characteristics are determined by external components. See Figure 13.
6.
With a 600
load. Output starts clipping with half of full scale digital input, which corresponds to a 0.5 Vrms output.
