■ Overview
YDA142 (D-3D) is a 12V single supply voltage, high-efficiency digital audio power amplifier IC. An audio power amplifier with a maximum output of 9.5W (RL=8Ω) × 2ch or 19W (RL=4Ω) × 1ch can be configured with one chip.
YDA142 has a “Pure Pulse Direct Speaker Drive Circuit” that directly drives speakers while reducing distortion of a pulse output signal and reducing noise on a signal, and it realizes the highest standard low distortion rate characteristics and low noise characteristics as compared with those of digital amplifier ICs in the same class. The circuit allows you to design a circuit with as few external parts as possible depending on use conditions because any filter is no longer required■ Features
