Note 4. This value is the full scale (0dB) of the input voltage. This voltage is input to LIN(RIN)+ and LIN(RIN)

− pin,

and is proportional to AVDD. (Vin = 0.58

× AVDD)

Note 5. PSR is applied to AVDD, DVDD and TVDD with 1kHz, 50mVpp.

Note 6. AVDD=28mA; DVDD=15mA@48kHz&5V, DVDD=26mA@96kHz&5V(typ).

Note 7. All digital input pins are fixed to DVDD or DVSS.
