Note 17.
最大入力電圧はAVDDと外部入力抵抗(Rin)に比例します。Vin
= 0.6 x AVDD x Rin / 20kΩ (typ).
Note 18.
ゲインは外部入力抵抗に反比例します。
Note 19. PLL Master Mode (MCKI=12.288MHz)で、PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR =
PMVCM = PMPLL = MCKO = PMBP = PMMP = M/S bits = “1”の場合です。このとき、MPWR pinの出
力電流は0mAです。
AVDD=11mA(typ), DVDD=4mA(typ).
EXT Slave Mode (PMPLL = M/S = MCKO bits = “0”)の場合: AVDD=10mA(typ), DVDD=3mA(typ).
Note 20. PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMBP bits = “1”の場
合です。
Note 21.
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。
