HT511
2.8W I2S Input Mono Class D Audio Amplifier

The HT511 is an easy-to-use, low-cost, I2S input mono Class D audio amplifier that drives up to continuous 2.8W into 4ohm speaker with 5V power supply, and 4.7W into 4ohm speaker with 6.5V power supply.

HT511 integrates an DA converter, the I2S interface supports up to 24bit width, 192kHz sample rate. built-in Class G boost converter supports adjustable boost voltages. The boost converter is automatically active only when a higher audio output power is required, which will significantly improve the efficiency and extends the playing time in battery supply applications.

The built-in Class D amplifier also integrates Anti-clipping Function (ACF). The gain of the amplifier is also adjustable using external resistors.The Device is available in TSSOP20 and QFN20 package.
