概览

NCP2890 是一款音频功率放大器，适用于手机等便携式通信设备应用。NCP2890 能够通过 5.0 V 电源向 8 Ω 负载提供 1.0 W 的连续平均功率，并通过 2.6 V 电源向 4 Ω 负载提供 320 mW 的连续平均功率。NCP2890 在提供高质量音频的同时，只需要极少的外部组件和最低的功耗。它具有低功耗关断模式，可通过以逻辑低电平驱动关断引脚来实现。NCP2890 包含的电路可防止在开启和关闭转换期间产生杂音。NCP2890 具有最大的灵活性，可提供一个外部控制的增益（带有电阻）以及一个外部控制的开启和关闭时间（带有旁路电容器）。由于其出色的 PSRR，它可以直接连接到电池，节省了 LDO 的使用。该器件采用 9 引脚倒装芯片 CSP 和 Micro8 封装。
