Overview

The HT513 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. HT513 integrates an DA converter, the I²S interface supports up to 32bit width, 192kHz sample rate. The built-in Class D amplifier also integrates Anti-clipping Function (ACF). The gain of the amplifier is also adjustable using external resistors.
