(2) Reference level (0 dB) is specified as 2-V rms input on VINL[1:6] and VINR[1:6] pins with PGA gain of –5.5 dB. (3) Unselected channel inputs are terminated to AGND with 0.33 µF. (4) fS = 96 kHz, system clock = 256 fS. (5) 2-V rms input is applied to all unselected channels, and input of selected channel is terminated to AGND with 0.33 µF. 7 Submit Documentation Feedback |
