TPA4861

具有关断模式和可选增益的 1W、单声道、模拟输入、AB 类音频放大器

The TPA4861 is a bridge-tied load (BTL) audio power amplifier capable of delivering 1 W of continuous average power into an 8- load at 0.2% THD+N from a 5-V power supply in voiceband frequencies (f < 5 kHz). A BTL configuration eliminates the need for external coupling capacitors on the output i • 1-W BTL Output (5 V, 0.11 % THD+N)\n• 3.3-V and 5-V Operation\n• No Output Coupling Capacitors Required\n• Shutdown Control (IDD = 0.6 µA)\n• Uncompensated Gains of 2 to 20 (BTL Mode)\n• Surface-Mount Packaging\n• Thermal and Short-Circuit Protection\n• High Supply Ripple Rejection Ratio (56 d;
