Note 9. PLL Slave ModeFCK pinからPLL基準クロックを入力する場合、S/(N+D)は、MIC→ADC75dB(typ),
DAC AOUT75dB(typ)になります。
Note 10. 出力電圧はAVDDに比例します。Vout = 0.6 x AVDD (typ) @LOVL bit = “0”
Note 11. LPF (Passband 20kHz 以下、Stopband Attenuation 250kHz 50dB以下) を通過後の電圧です。
Note 12. 測定点は SPP pin /SPN pin です。
Note 13. fs=48kHz,Measurment Frequency=20Hz~20kHzの場合、Output Noise Level=-68dBV(typ.)になります。
Note 14. Figure 44 において、Load Impedance はシリーズ抵抗と 1kHz における圧電スピーカの抵抗成分の合計
です。Load Capacitance は圧電スピーカの容量成分です。圧電スピーカを使用する場合、SPP, SPN pin
にそれぞれ10以上のシリーズ抵抗を接続してください。
Note 15. PLL Master Mode (MCKI=12MHz)で、PMMP = PMADC = PMDAC = PMPFIL = PMSPK = PMVCM =
PMPLL = MCKO = PMAO = M/S =“1”の場合です。このとき、MPI pinの出力電流は0mAです。
EXT mode(PMPLL=MCKO=M/S=“0”) AVDD+DVDD = (typ)6mA@fs=8kHz (typ)11mA
@fs=48kHz になります。
Note 16.Class-D Speakerの負荷が8Ω+10uHの場合です。負荷が3F+10 x 2の場合、3.0mA @SVDD=3.8V(typ)
なります。
Note 17. 全てのディジタル入力ピンをDVDDまたはVSS2 に固定した時の値です。
