YDA139 D- 4 STEREO 2.5W DIGITAL AUDIO POWER AMPLIFIER Overview YDA139 (D-4) is a digital audio power amplifier IC with maximum output of 2.5W (RL=4 )×2ch. YDA139 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 the same 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. YDA139 has the power-down function which can minimize the power consumption in the standby state.
