芯片型号:A7022

功能特点

The A7022 is a cost-effective 4W-per-channel stereo filter-free Class-D audio amplifier designed with Apexoneˉs patent pending technologies and architecture. The chip features very low 0.02%-THD+N, high 94dB-SNR, high 92%-efficiencies and good 73dB-PSRR at 217Hz. Large output power, high efficiencies, low THD+N, high SNR, good PSRR and differential architecture together provide the best immunity to noise for portable and semi-portable devices. Additionally, the A7022ˉs fast startup time and low shutdown current make the A7022 an ideal choice for both powered speakers and portable devices -- the A7022 can drive speakers as low as 4-Ohm or even lower.
