HAA3603是一款模拟输入立体声高效D类音频功率放大器。它需要最少的外部组件，并运行单个8V至14.4V电源。该设备可以驱动2x4Ω扬声器，并在12V电源电压下提供2X15W峰值输出功率（THD+N=1%）。在PBTL模式下，它可以向2Ω扬声器提供高达1x30W的峰值输出功率，同时提供高达88.5%的高效率。

HAA3603具有SSM（扩频调制）、AERC（有源边缘速率控制）和去相位功能，以抑制EMI，从而在输出端使用廉价的铁氧体磁珠滤波器，同时满足降低系统成本的EMC要求。

HAA3603具有UVP（欠电压保护）、OVP（过压保护）、直流扬声器保护、OCP（过电流保护）和OTP（过温保护）。所有这些保护都可以自动恢复。

HAA3603在ETSSOP-28L包中提供。

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.

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.

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.

HAA3603 is available in ETSSOP-28L package.
