具有IVSENSE、超低IQ和掉电保护功能的28V数字输入DG类放大器

MAX98397是一款高效率、单声道DG类扬声器放大器，具有业界出色的静态功耗，集成了扬声器电流和电压检测(IVSENSE)、掉电保护引擎(BPE)和动态裕量跟踪(DHT)功能。该器件支持高达192kHz的采样速率、更高的通带（对于fS > 50kHz），并为通过放大器的超声信号提供旁路路径，使其不会因音频处理而衰减，因此还有助于实现超声应用。通过高精度的输出电流监控(ISENSE)和电压监控(VSENSE)，主机设备能够运行扬声器保护算法。扩频调制(SSM)和边缘速率控制可充分降低EMI，并且无需像传统D类器件中一样进行输出滤波。\n\n 为了实现业界出色的静态功耗，DG类架构采用 • 宽输入电源范围（3V至28V）\n• DG类操作可实现业界出色的静态功耗\n• 25.3mW（VPVDD = 24V、VVBAT = 5.0V时）\n• 超低噪底\n• 117.8dB动态范围\n• 低失真\n• -85dB THD+N（为4Ω负载提供6W功率时，f = 1kHz）\n• -80dB THD+N（为8Ω负载提供1W功率时，f = 6kHz，FSW = 650kHz） \n• 输出功率：\n• 为4Ω负载提供26W，VPVDD = 16V，THD+N = 1%\n• 为8Ω负载提供51W，VPVDD = 28V，THD+N = 10%\n• 为4Ω负载提供10;
