LC32D44E/S/RU-BK/GY (1st Eddition)
5 – 8
8. IC2701 (VHiYDA147SZ-1Y)
High-efficiency digital audio power amplifier IC with maximum power output of 20W (Vddp=14V, RL=4) x 2ch.
It incorporates the “DRC (Dynamic range compression)” function. Since the volume is increased at low volume level and is decreased at high volume
level, it is possible to prevent sudden volume change. It is also provided with the “power limiter” which can set the output limit.
