STEREO 60W-100W DIGITAL AUDIO POWER AMPLIFIER CONTROLLER

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.
YDA136 realizes a high-standing audio characteristic that is lower noise and distortion rate by performing an analog
feedback from PowerMOSFET output, and by using Yamaha’s unique modulation method.
YDA136 also equips a function (Over current detection function) which protects a circuit from a short of speaker output
terminal (after the LC filter) and a function (Supplied voltage detection function) which prevents a malfunction by
detecting a power supply falling.
Moreover, it has a function (Clock stop detection function) to protect a circuit by detecting a stop termination of PWM
carrier clock and a function (High-temperature detection function) to protect a circuit by detecting the unusual
high-temperature condition of it-self.
At last, by making three YDA136 to daisy-chain connection, the audio system of 6ch is easily realizable.
