series at each input pin. Full-differential input is not available at MGAIN1-0 bits = “00”. Maximum input voltage
of LIN+, LIN−, RIN+ and RIN− pins is proportional to AVDD voltage, respectively.
Vin = |(L/RIN+) − (L/RIN−)| = 0.123 x AVDD (max)@MGAIN1-0 bits = “01”, 0.022 x AVDD
(max)@MGAIN1-0 bits = “10”.
When the signal larger than above value is input to LIN+, LIN−, RIN+ or RIN− pin, ADC does not operate
normally.
Vin = 0.6 x AVDD(typ)@MGAIN1-0 bits = “00” (0dB).
MCKO bit = “0”. MPWR pin outputs 0mA. AVDD=6.4mA(typ), DVDD=1.6mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”): AVDD=5.7mA(typ), DVDD=1.3mA(typ).
