YAMAHA CORPORATION YDA135
YDA135 is digital audio power amplifier controller IC that is output power of 20W/channel on a 12V power supply operation. This IC is combined with the general purpose Power MOSFET (hereafter called Power MOSFET) that are connected through BTL can configure an audio power amplifier with output power of 5W or 20W. This IC accepts analog signal, converts it into digital pulse signal by the digital modulation circuitry and outputs the digital pulse signal for driving Power MOSFET.| Part No. | YDA135 |
