Note 7. プラス入力ピンとマイナス入力ピンの差分です。ACカップリングコンデンサを各入力ピンにシリー
Note 8. 出力電圧はAVDDに比例します。Vout = 0.75 x AVDD (typ)。
Note 9. 入力電圧はAVDDに比例します。Vin = 0.107 x AVDD (typ)@MGAIN1-0 bits = “01” (+15dB), Vin = 0.6 x
Note 10. 78dB(typ)@MGAIN=0dB, 72dB(typ)@MGAIN=+30dB
Note 11. 89dB(typ)@MGAIN=0dB, 77dB(typ)@MGAIN=+30dB
Note 12. 100dB(typ)@MGAIN=0dB, 80dB(typ)@MGAIN=+30dB
Note 13. PLL Master Mode (MCKI=12MHz)で、PMADL = PMADR = PMVCM = PMPLL = PMMP = M/S bits = “1”,
Note 14. 全てのディジタル入力ピンをDVDDまたはDVSSに固定した時の値です。

Signal Frequency=1kHz; 16bit Data; Measurement frequency=20Hz ∼ 20kHz; unless otherwise specified)
Power Up (PDN pin = “H”) (Note 13)
Power Down (PDN pin = “L”) (Note 14)
ズに接続して下さい。MGAIN1-0 bits = “00”のとき差動入力は使用禁止です。LIN+, LIN−, RIN+, RIN−
pinの最大入力電圧はそれぞれAVDDに比例します。Vin = |(L/RIN+) − (L/RIN−)| = 0.123 x AVDD
(max)@MGAIN1-0 bits = “01”, 0.022 x AVDD (max)@MGAIN1-0 bits = “10”.
この電圧を越える信号が入力された場合、ADCの動作は保証できません。
AVDD(typ)@MGAIN1-0 bits = “00” (0dB)
MCKO = “0”の場合です。このとき、MPWR pinの出力電流は0mAです。
AVDD=6.4mA(typ), DVDD=1.6mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”)の場合: AVDD=5.7mA(typ), DVDD=1.3mA(typ).
Bypass Mode (THR bit = “1”, PMADL = PMADR = M/S bits = “0”), fs=8kHzの場合: AVDD=1µA(typ),
DVDD=150µA(typ).
