Note 16. Output voltage is proportional to AVDD voltage. Vout = 0.6 x AVDD (typ).
Note 17. Output voltage is proportional to AVDD voltage. Vout = (RCP) − (RCN) = 0.59 x AVDD (typ)@−6dBFS.
Note 18. Load Capacitance for VSS1.
Note 19. Output voltage is proportional to AVDD voltage. Vout = 0.3 x AVDD (typ)@−6dBFS.
