The A2430 is a digital audio power amplifier IC with maximum output of 2.1W (RL = 4Ω) x 2ch, 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 .
