HAA3603

    HAA3603是一种模拟输入、立体声、高效级D音频功率放大器。它需要最少的外部设备组件和操作单个8V至14.4V电源。该设备可驱动2x4Ω扬声器并提供2X15W功率12V电源下的峰值输出功率(THD+N=1%)电压在PBTL模式下,它可以提供高达1x30W的峰值向2Ω扬声器输出功率,同时提供敢达88.5%的功率高效率。
    HAA3603具有SSM(扩频调制),AERC(主动边缘速率控制)和去相位功能抑制EMI,使用廉价铁氧体在满足EMC要求的同时,在输出端安装珠状过滤器以降低系统成本。
    HAA3603具有UVP(欠电压保护)、OVP(过电压保护)、直流扬声器保护、OCP(过电流保护)、OTP(过温保护)。全部这些保护可以自动恢复。
    HAA3603提供ETSSOP-28L封装。

        The HAA3603 is an analog input, stereo, high efficiency Class D audio power amplifier. It requires minimal external components and operates a single 8V to 14.4V power supply. The device can driver 2x4Ω speakers and delivering 2X15W peak output power (THD+N=1%) at 12V power supply voltage. When PBTL mode, it can deliver up to 1x30W peak output power into a 2Ω speaker while offering up to 88.5% high efficiency.
        The HAA3603 features SSM (spread spectrum modulation), AERC (active edge rate control) and De-phase function to suppress EMI which enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements for system cost reduction.
        The HAA3603 features UVP (under-voltage protection), OVP (over-voltage protection), DC speaker protection, OCP (overcurrent protection), OTP (over-temperature protection). All of these protections can be recovered automatically.
        The HAA3603 is available in ETSSOP-28L package.
