Heroic HT81298
The HT81298 is a stereo Class D audio amplifier integrated a boost converter. With wide input voltage range, HT81298 supports applications with single cell, two cell Lithium batteries, or 5V power supply and so on, and can drive two speakers in BTL mode or one speaker in paralleled PBTL mode. It also implements an adjustable switching peak current limit function through external resistors.| Part No. | HT81298 |
