说明

TPA3220 是一款可在全功率、空闲和待机状态下实现高效操作的焊盘朝下的 D 类放大器。该器件 采用 具有高达 100kHz 带宽的闭环反馈,从而在音频频带内提供低失真并提供出色的质量。该器件以 AD 或低空闲电流 HEAD(高效 AD)调制运行,并可为 4Ω 负载提供 2 x 60W 的连续功率或 2 x 110W 的峰值功率(底部的散热垫连接到 PCB)。

TPA3220 具有 单端或差分模拟输入接口,该接口最高支持 2VRMS 的电压并具有四种可选增益:18dB、24dB、30dB 和 34dB。TPA3220 还实现了大于 90% 的效率、低空闲功率 (<0.25 W) 和超低待机功耗 (<0.1 W)。这是通过使用 70mΩ MOSFET、经优化的栅极驱动方案和低功耗操作模式实现的。TPA3220 包含用于轻松集成在单电源系统中的内置 LDO。为了进一步简化设计,该级器件集成了重要的保护 功能, 包含低压、逐周期电流限制、短路、削波检测、过热警告和关断以及直流扬声器保护。
