Figure 1: Measured ADC performance of the LINEIN pin.
Measured ADC performance of the LINEIN pin. X-axis is rms amplitude of 1 kHz sine input.
Curves are unweighted signal-to-noise ratio (blue), A-weighted signal-to-noise ratio (green),
and unweighted signal-to-distortion ratio (red). Sampling rate of ADC is 48 kHz (master clock
12.288 MHz), noise calculated from 0 to 20 kHz.
