HT562 2X40W I 2S Input Stereo Class D Amplifier
來 源： 時 間：2023-11-15
? GENERAL DESCRIPTION
The HT562 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 HT562 can be configured to drive two speakers in stereo BTL mode or mono PBTL mode.
The HT562 also includes hardware and software control modes, integrated digital clipper, and a wide power supply operating range to enable use in a multitude of applications. Advanced EMI Suppression with Spread Spectrum
Control enables the use of inexpensive ferrite bead filters while meeting EMC requirements for system
cost reduction.
An optimal mix of thermal performance and device cost is provided in the 80-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.
