  • TPA3126D2: TPA3116D2をTPA3126D2に置き換え

    Resolved
    Part Number: TPA3126D2 Other Parts Discussed in Thread: TPA3116D2 皆さんこんにちは 私も 皆さんこんにちは 私もTPA3116D2をTPA3126D2に置き換えテストをしています。 TPA3116D2は正弦波4Ω40Wステレオで連続動作しますが、TPA3126D2は2分程度で間欠動作となってしまいます。 IC放熱板の温度はTPA3116D2は最大143°Cですが、TPA3126D2は65°C程度で間欠動作となります。 放熱板に送風すると連続動作します…
