Description
The YDA138-E is a high efficient digital audio power amplifier IC that operates with a single 12V power supply. It can be configured to provide a maximum output of 10W (RL=8Ω)×2ch or 20W (RL=4Ω)×1ch with one chip. It features the "Pure Pulse Direct Speaker Drive Circuit" which directly drives speakers while reducing distortion and noise on the signal, resulting in low distortion rate characteristics and low noise characteristics. The YDA138-E also has a circuit design with fewer external parts, making it versatile for various applications.
