YDA148
D-510
STEREO 5W-15W DIGITAL AUDIO POWER AMPLIFIER
Overview
YDA148 (D-510) is a high-efficiency digital audio power amplifier IC with the maximum output of 15W
× 2ch. YDA148 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 filter less design allows circuit design with fewer external parts to
be realized depending on use conditions. YDA148 features Power Limit Function, Non-clip Function,
and DRC (Dynamic Range Control) Function that were developed by Yamaha original digital amplifier
technology. YDA148 has overcurrent protection function for speaker output terminals, high temperature
protection function, and lowsupply voltage malfunction prevention function.
