YDA138 - STEREO 10W DIGITAL AUDIO POWER AMPLIFIER
of operating functions *Digital Amplifier Function YDA138 has digital amplifiers with analog input, PWM pulse output, Maximum output of 10W (RL=8Ω)×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
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
