GENERAL DESCRIPTION
HT6808 is an Ultra Low-EMI Anti-Clipping stereo
Class D audio power amplifier IC with maximum
output power of 3W, efficiency up to 90%.
HT6808 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 improves the sound
quality, creating a very comfortable musical
enjoyment, and to protect the speakers from
overload damage. In addition Sound quality and
output power can be freely set by external
resistance or capacitance of ACRC.HT6808 also
supply ACF OFF mode.
HT6808 has excellent EMI radiation suppression
characteristics, well below the FCC Part15 Class B
standards, simplifying system design and lowering
system cost.
HT6808 has a “Pure Pulse Direct Speaker Drive
Circuit” which directly drives speakers while
reducing distortion of pulse output signal and
reducing noise on the signal, and realizes the
highest standard low distortion rate characteristics
and low noise characteristics among digital
amplifier ICs for portable use.
HT6808 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.
HT6808 is available in Pb-Free TSSOP-20 and
QFN-20 package.
