4通道音频功率放大器IC概念
- CD 0.13μm工艺
+B浪涌的高韧性工艺
- 对于噪声的抗干扰性强
易于设计EMI／EMC／BCI等
- 专用输出直流偏移检测（东芝专利）
该集成电路可对扬声器端子进行专用直流偏移电压检测。可以实现一种系统以防止由于产生直流偏移电压而导致扬声器音圈烧坏。
- 小型扁平封装
- 全新线性高效AMP“TB级”
与其它AMP相比，温度降低了大约20-40摄氏度。
- 6V巡航设计
- 诊断功能
AB／TB级AMP的温度数据
测试条件
Vcc＝13.2V，f＝1kHz，RL＝4Ω，Pout＝0.4W×4ch工作，Ta＝25℃
散热器热阻：6.5℃/W（铝制尺寸：85×85×2mm）
东芝原创线性高效放大器：TB级实现了高效TCB701FNG（50W）／702FNG（45W）
高效（东芝专利）
功耗比较
- vs传统AB级AMP >>> 减少80%
- vs数字D级AMP >>> 在Pout < 4W时接近
低BOM成本
合理的外部元件
- vs传统AB级AMP >>> 相同
- vs数字D级AMP >>> 不到一半
专用输出直流偏移检测（东芝专利）
