Description
The YDA131-EZE2 is a high efficient digital audio power amplifier IC that operates on a single 5V power supply. This IC is capable of providing output power of 2.5W/channel. By adopting Yamaha's proprietary modulation system, the device provides low distortion and high signal to noise ratio. The YDA131-EZE2 accepts analog signal, converts it into digital pulse, and outputs the signal from the large current capacity buffers. It is suitable for various audio applications.
