YDA136 D- 60 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=6Ω) and 100Wx2ch (Supplied voltage=40V, RL=6Ω). 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 syst.
