2x3Walts Class-D Audio Power Amplifier

The LPA2150 is a high efficiency, 2x3.0W class-D audio power amplifier. A new developed filterless PWM modulation architecture further reduces EMI and THD+N, as well as eliminates the LC output filter, reducing external component count, sys cost, and simplifying design. Operating in a single 5V supp ·Unique Modulation Scheme Reduces EMI Emissions\n·Efficiency at 3.6V With an 8-Ω Speaker:       − 90% at 400 mW       − 82% at 100 mW\n·Low 5mA Quiescent Current\n·0.5μA Shutdown Current\n·2.5V to 6V Wide Supply Voltage\n·Shutdown Pin has 1.8V Compatible Thresholds\n·Optimized PWM Output Sta;
