Note 5. Full-scale voltage of analog inputs when IPGA0 and IPGA1 bits are “0” and are set to 0dB. Its voltage is
Note 6. IPGA1 does not have a gain table of LINE side.
Note 7. ADC0 is input from INTL0/INTR0 or EXTL/EXTR or LIN/RIN and it measures included in IPGA0. The gain of
Note 8. Analog output voltage is proportional to VREF. Vout = 0.6 x VREF.
Note 9. All digital input pins except for PDN pin are held VT or DGND, and PDN pin is held DGND.

Normal Operation (PDN= “H”)
Power-down mode (PDN= “L”) (Note 9)
All Power ON (PM4-0= “1”)
IPGA0+ADC0+IPGA1+ADC1 (PM3-0= “1”)
DAC (PM4= “1”)
proportional to VREF. Vin = 0.6 x VREF.
IPGA0 is set 0dB. ADC1 is input from INTL1/INTR1 and it measures included in IPGA1. The gain of IPGA1 is
set 0dB.
DC-offset in “IPGA0+ADC0” and “IPGA1+ADC1” are cancelled by internal HPF.
