音频功率放大器,3.0 W,无滤波,D 级
Last Shipments
NCP2823A/B 是成本高效的单声道音频功率放大器,适用于便携式电子设备。NCP2823A 适用于 8 Ω 运行,NCP2823B 可以低至 4.0 Ω 的扬声器阻抗运行。例如,NCP2823B 能够基于 5.0 V 电源,在桥接负载 (BTL) 配置中为 4.0 Ω 负载提供 3 W 的连续平均功率。在相同条件下,NCP2823A 可以不到 10% 的 THD+N 向 8.0 Ω BTL 负载提供 1.5 W 功率。对于蜂窝电话听筒或 PDA,它可以带来空间和成本节省,因为使用直感传感器时无需输出滤波器。它具有高于 90% 的能效和极低的关断电流,因此延长了电池寿命,大幅降低了结温度。

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.)
