(Ta=25°C; AVDD=DVDD=HVDD=3.0V, AVSS =DVSS=HVSS=0V; fs=44.1kHz; BOOST OFF; Signal Frequency
=1kHz; Measurement band width=20Hz ∼ 20kHz; unless otherwise specified)
Note 6. The signal inputs are AINL1/AINR1 or AINL2/AINR2. The value of the IPGA is set to 0dB. On-chip HPF
Note 7. DACL=DACR= “1”, MINL=MINR=LIN=RIN= “0”, and ATTL=ATTR=0dB.
Note 8. AC Load
Note 9. A resistor greater than 6.8Ω is inserted in series.
Note 10. DACM= “1”, LINM=RINM=MINM= “0”, ATTL=ATTR=ATTM=0dB, and common mode signal is input to
Note 11. PSR is applied to AVDD, DVDD and HVDD with 1kHz, 50mVpp.
