YDA143 STEREO 15W DIGITAL AUDIO POWER AMPLIFIER

of operating functions *Digital Amplifier Function YDA143 has digital amplifiers with analog input, PWM pulse output, Maximum output of 15W (RL=4Ω) 2ch. Distortion of PWM pulse output signal and noise of the signal is reduced by adopting “Pure Pulse Direct Speaker Drive Circuit” First Stage Ampl.

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 ra.
