概述
The HT566 is a stereo Class D audio amplifier with multiple audio format port (I2S, LJ, RJ, TDM). It supports a variety of audio clock configurations. The outputs of the HT566 can be configured to drive two speakers in stereo BTL mode or mono PBTL mode.
The HT566 also includes hardware and I2C control modes, integrated digital clipper, spread switching frequency for Class D, and a wide power supply operating range to enable use in a multitude of applications.
An optimal mix of thermal performance and device cost is provided in the 120-mΩ RDS(ON) of the output MOSFETs. Additionally, a thermally enhanced 36-
Pin QFN provides excellent operation in the elevated ambient temperatures found in modern consumer electronic devices.
