YDA147 Datasheet Stereo 5w-15w Digital Audio Power Amplifier

Manufacturer: YAMAHA CORPORATION

Overview: YDA147 D- 515 STEREO 5W-15W DIGITAL AUDIO POWER AMPLIFIER Overview YDA147 (D-515) is a high-efficiency digital audio power amplifier IC with the maximum output of 15W × 2ch. YDA147 has a “Pure Pulse Direct Speaker Drive Circuit” that directly drives speakers while reducing distortion of pulse output signal and reducing noise on the signal, which realizes the highest standard low distortion rate characteristics and low noise characteristics among digital amplifier ICs in the same class. In addition, supporting filterless design allows circuit design with fewer external parts to be realized depending on use conditions.
