PCM to Class D Amplifier
Overview
The AR35S13B is a high-performance digital Class D Amplifier IP for mono speaker playback application. The amplifier converts 16-24 bits digital PCM (pulse code modulation) from SoC into PWM (pulse-width modulation) data. The IP is capable of providing 0.1% THD+N performance in light loading condition. The IP is fabricated in SMIC 0.13um 1P6M logic process.
