*6. 電圧は全てグランドピンに対する値です。
*7. 各電源の立ち上げ/げシーケンスを考慮する必要はありません。電源立ち上げ時に内部回路が不
になることを避けるためPDN pin = “L”の状態で各電源を立ち上げ、全ての電源が立ち上がった後
PDN pin = “H”にしてください。
*8. 周辺デバイスが電源 ON の状態で AK4619の電源を OFFにしないでください。AK4619内部の
護ダイオードを通して SDA pin, SCL pin 0V 接続されるため同じ I2C Bus上のデバイスは
信ができなくなります。
注意: 本データシートに記載されている条件以外のご使用に関しては、当社では責任を負いかねます
ので、十分ご注意ください。

Notes:
*18. 各振幅特性の周波数はfs(サンプリングレート)に比例します。ハイパスフィルタの特性は含まれ
ていません。
*19. Group Delay(群遅延)は、ディジタルフィルタによる演算遅延で、アナログ入力信号が入力されて
からシリアルデータ出力ピンに該当データのMSBが出力されるまでの時間です。最大+1[1/fs]
誤差を生じる可能性があります。HPFによる群遅延も含みます。
