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.
YDA147 features Power Limit Function, Non-clip Function, and DRC (Dynamic Range Control) Function that were
developed by Yamaha original digital amplifier technology.
YDA147 has overcurrent protection function for speaker output terminals, high temperature protection function, and
lowsupply voltage malfunction prevention function.
