音频功率放大器,立体声耳机,135 mW
Last Shipments
NCP2809 是一款经济高效的立体声音频功率放大器,能够向 16Ω 负载提供每沟道 135mW 的连续平均功率。NCP2809 音频功率放大器专门设计用于通过低电源电压提供高质量的输出功率,且仅需要很少的外部元件。由于 NCP2809 不需要自举电容器或缓冲网络,因此非常适合于低功耗便携式系统。NCP2809A 的内部增益为 0 dB,而特定的外部增益可通过 NCP2809B 设置。如果应用允许,则该器件提供的虚拟接地点可连接到耳机的中点。在此种情况下,可以移除通常使用的两个外部重型耦合电容器。否则,您也可以使用外部耦合电容器在单端模式下同时执行两个输出。由于其出色的 PSRR,它可以直接连接到电池,从而节省了 LDO 的使用。

Re-calculate Data
Data is based on the following assumptions.
Note: The temperature and confidence level may be adjusted to your requirements.
Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
