? GENERAL DESCRIPTION
The HT760 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 HT760 can be configured to
drive two speakers in stereo BTL mode or mono
PBTL mode.
The HT760 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 150-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.
? APPLICATIONS
