Power Supplies:
Power Supply Current: AVDD+DVDD
Power Up (PDN pin = “H”) (Note 12)
Power Down (PDN pin = “L”) (Note 13)
Note 7. The voltage difference between AIN+ and AIN
pins. AC coupling capacitor should be inserted in series at each
input pin. Full-differential input is not available at MGAIN1-0 bits = “00”. Maximum input voltage of AIN+,
AIN
pins is proportional to AVDD voltage, respectively.
Vin = |(AIN+)
(AIN
)| = 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 AIN+, AIN
pin, ADC does not operate normally.
Note 8. Output voltage is proportional to AVDD voltage. Vout = 0.75 x AVDD (typ).
Note 9. Input voltage is proportional to AVDD voltage. Vin = 0.107 x AVDD (typ)@MGAIN1-0 bits = “01” (+15dB),
Vin = 0.6 x AVDD(typ)@MGAIN1-0 bits = “00” (0dB).
Note 10. 80dB(typ)@MGAIN=0dB, 70dB(typ)@MGAIN=+30dB
Note 11. 89dB(typ)@MGAIN=0dB, 75dB(typ)@MGAIN=+30dB
Note 12. PLL Master Mode (MCKI=12MHz), PMADC = PMVCM = PMPLL = PMMP = M/S bits = “1” and MCKO bit
= “0”. MPWR pin outputs 0mA. AVDD=4.5mA(typ), DVDD=1.5mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”): AVDD=3.8mA(typ), DVDD=1.2mA(typ).
