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.
