YDA138 D- 3 STEREO 10W DIGITAL AUDIO POWER AMPLIFIER ■Overview YDA138 (D-3) is a high efficient digital audio power amplifier IC that operates with a single 12V power supply. An audio power amplifier with a maximum output of 10W (RL=8Ω)×2ch or 20W (RL=4Ω)×1ch can be configured with one chip. YDA138 has a “Pure Pulse Direct Speaker Drive Circuit” which directly drives speakers while reducing distortion of pulse output signal and reducing noise on the signal, and realizes the highest standard low distortion rate characteristics and low noise characteristics as 10W-class of output digital amplifier IC. In addition, circuit design with fewer external parts can be made depend on the condition of use because corresponds to filter less. YDA138 has 50mW (RL=32Ω)×2ch Class AB headphone amplifiers.
