Note 2 . Analog Input and Output voltage (Full-Scale voltage:0dB) scale with VA.
IPGA: 0.57 x VA(typ.), DAC : 0.6 x VA(typ).
3 . ADC is input from LIN1/RIN1 or LIN2/RIN2 and it measures included in IPGL/IPGR. The value of
IPGL/IPGR is set 0dB.
Internal HPF removes offset in the ADC, IPGL/IPGR.
4 . Measured by AD725C(SHIBASOKU), RMS mode.
5 . In case of the power-down mode, all digital input pins including clock(MCLK, BCLK, LRCK) pins are
held VD or DGND.
