具有内置专用偏移检测功能的汽车音响用电流反馈4通道功率放大器：TCB501HQ
“TCB501HQ”集成了新开发的专用偏移检测电路。
在放音过程中进行常规的偏移检测很难，而采用该专用电路即便是在放音过程中也能检测因输入电容和其它来源泄漏导致的输出直流偏移电压，从而可防止扬声器烧坏。
它也集成了高端高保真音响中所采用的电流反馈系统类型。它防止了声音在较宽带宽范围内的质量下降，保证了一致的声音品质。
- 最大输出功率：
49W×4通道（VCC＝15.2V，RL＝4Ω，最大功率） - 输出噪声电压：4µVrms（BW=DIN Audio）
- 工作电源电压范围：
6至18V（4Ω），6至16V（2Ω） - 封装：HZIP25-P-1.00F
嵌入式功能和特点
- 高输出功率，低失真
- 内置静音和待机功能、偏移检测和高边开关驱动IC
- 6V运行（发动机怠速减速能力）
- 各种保护电路（热关断、过电压、对VCC短路、对地短路和对负载短路）
