STEREO 2.5W DIGITAL AUDIO POWER AMPLIFIER
Outline
The YDA131 is the 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, which is at the highest level as a device on a single
5V power supply. By adopting Yamaha's proprietary modulation system, the device provides low distortion and high
signal to noise ratio at the highest level among digital amplifiers in the equivalent class.
This IC accepts analog signal, converts it into digital pulse by the digital modulation circuitry and outputs the signal
from the large current capacity buffers. The digital pulse signal that is outputted from the output buffer is converted
into audio signal through an external low pass filter, and sent to the speakers.
This IC has the overcurrent detection function that detects short-circuiting of speaker terminal end and the high
temperature detection function that detects abnormal high temperature.
With the overcurrent detection function, this IC generates a warning signal when the current that flows in the output
buffers of left and right channels exceeds a fixed value. With the high temperature detection function, this IC
generates a warning signal when the junction temperature becomes abnormal.
Furthermore, this IC builds in function that mute an audio output and shut off all functions of the IC. By this function,
power consumption is restrained at the minimum.
