GENERAL DESCRIPTION
HT8692 integrates a boost converter with a
filter-less stereo class D audio power amplifier to
provide 6.5W continuous power into a 4speaker,
and 8.0W continuous power into a 3speaker
when operating from a Li-battery voltage boosted
to 7.0V. Meanwhile, the boost output voltage is
adjustable.
HT8692 features Anti-Clipping Function (ACF)
which detects output signal clip due to the over
input signal and suppresses the output signal clip
automatically. Also, the ACF function can adapt the
output clip caused by power supply voltage down
with battery. It can significantly improve the sound
quality, creating a very comfortable musical
enjoyment, and to protect the speakers from
overload damage. It also supplies ACF OFF mode.
Class AB amplifier mode is also available for
HT8692. Once the EMI Interference from class D
and Boost Converter becomes an annoying
problem, HT8692 can be changed into Class AB
mode.
HT8692 has a filter-less modulation circuit
which directly drives speakers while realizes low
distortion and low noise characteristics. Thanks to
filter-less, circuit design with fewer external parts
can be made in portable applications.
HT8692 has the independent Shutdown
function which can minimize the power
consumption at standby and MUTE function. As for
protection function, over current protection function
for speaker output terminals, over temperature
protection function, and low supply voltage
malfunction preventing function are also prepared.

*3: Absolute Maximum Ratings is values which must not be exceeded to guarantee device reliability. With a system in
which supply voltage might exceed supply voltage of PVDD/GND, external diodes are recommended to be used to
assure that the voltage does not exceed the absolute maximum rating.
