YDA143 Datasheet Stereo 15w Digital Audio Power Amplifier

Manufacturer: YAMAHA CORPORATION

Overview: YDA143 D- 3M STEREO 15W DIGITAL AUDIO POWER AMPLIFIER ■Overview YDA143 (D-3M) 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 15W (RL=4Ω) 2ch can be configured with one chip. YDA143 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 15W-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. YDA143 has 50mW (RL=32Ω) 2ch Class AB headphone amplifiers. YDA143 provides Over-current protection function for speaker output terminals, IC thermal protection function, and POP noise reduction function as well as power-down function and output mute function.
