该TAS5708是20瓦，高效率，数字化驱动立体声桥接式扬声器的音频功率放大器。 A 32-bit data channel eliminates the need for pre-processing expansion and retains signal integrity without sacrificing dynamic range. The digital filter with a fully programmable digital audio processor enables designers to customize the best tone speaker in a small chassis. A programmable DRC can adjust an expandable design power level while also enabling night mode listening mode.

The closed-loop architecture allows the device to work poorly managed supplies. When the feedback architecture in Figure 1 below benefits, the noisy supply (500mVpp ripple at 1kHz) is modulated into a 10kHz audio input.

characteristic

• Audio input/output
  • An 8 Ω load at 20 W is supplied from an 18 V supply
  • PVCC范围宽（10 V至​​26 V），3.3 V数字电源
  • Supports one serial audio input (8 kHz - 48 kHz sample rate) (chick/RJ/i^{2 seconds}）
  • Power level feedback can be derived from poorly managed regulated power supplies
• Audio/pulse width modulation processing
  • Factory-calibrated automatic rate detection of internal oscillators
  • High-end 32-bit data channel audio processor
  • 14扬声器均衡二阶滤波器
  • Dynamic range control (gold)
• merit
  • 情商：提高音频性能扬声器均衡
  • 刚果民主共和国：启用扬声器保护和夜间模式听力。
  • Autobank Switch: Three different sample rate coefficients, no need to pre-install update the sample rate when the coefficient changes
  • Automatic detection: Automatic detection of sample rate changes by external microprocessor intervention is not required
  • Closed-loop power stage: Opens up a wide PVCC operating range and reduces power supply ripple distortion
