Performance

Frequency Response

The above graphs show the frequency response of the ADC1 when it is operating at a 192-kHz sample rate. Note that the amplitude response is down by less than 0.05 dB at 10 Hz and 80 kHz. The bass response extends well below the 10-Hz limitation of the measurement equipment, and the high-frequency analog response extends well above the 96 kHz bandwidth of 192 kHz digital audio.
