Description
YDA148-QZE2 is a high-efficiency digital audio power amplifier IC. It is designed for 12V single supply voltage. With one chip, it can configure an audio power amplifier with a maximum output of 9.5W (RL=8Ω) × 2ch or 19W (RL=4Ω) × 1ch. This IC features a "Pure Pulse Direct Speaker Drive Circuit" that directly drives speakers, reducing distortion and noise on the signal. It provides low distortion rate characteristics and low noise characteristics compared to other digital amplifier ICs. Additionally, the YDA148-QZE2 requires fewer external parts, as any filter is no longer required depending on the use conditions.
