Description
The YDA174-QZE2 is a high efficient digital audio power amplifier IC that operates on a single 5V power supply. It provides an output power of 2.5W/channel, which is at the highest level for devices on a single 5V power supply. With Yamaha's proprietary modulation system, this IC delivers low distortion and high signal to noise ratio, making it one of the best in its class of digital amplifiers. It accepts analog signals, converts them into digital pulses, and outputs the signal through large current capacity buffers. The output pulse signal can be converted into audio through an external low pass filter and sent to the speakers.
