■ Outline

YDA136 (D-60) is a high efficient and high output digital audio power amplifier controller IC. By combining a general purpose PowerMOSFET (hereafter called PowerMOSFET) which is connected with YDA136 and BTL, it is able to compose a high efficient audio power amplifier such as 60Wx2ch (Supplied voltage=32V, RL=6?) and 100Wx2ch (Supplied voltage=40V, RL=6?).

YDA136 has 24bit 192kHz (max) DAC and 6 to -73dB（1dB Step） of electron volumes in addition to a digital amplifier controller, and supports a digital audio signal input. Furthermore, it also supports an analog audio signal input with DAC bypasses.
