3 W无滤波D类音频功率放大器

The A21SP16 is a differential class-D BTL power amplifier. It is able to drive up to 2.3 W into a 4 Ω load and 1.4 W into a 8 Ω load at 5 V. It achieves outstanding efficiency (88% typ.) compared to classical Class-AB audio amps.\n\n The gain of the device can be controlled via two external gain • Operating from VCC = 2.4 V to 5.5 V \n• Standby mode active low \n• Output power: 3 W into 4 Ω and 1.75 W into 8 Ω with 10% THD+N max and 5 V power supply \n• Output power: 2.3 W @ 5 V or 0.75 W @ 3 V into 4 Ω with 1% THD+N max \n• Output power: 1.4 W @ 5 V or 0.45 W @ 3 V into 8 Ω with 1&;
