采用非对称电源(单电源)供电时 TDA8933B 器件的简化应用电路。 TDA8933B 集成了三个集成的半电源电压
缓冲器,以简化 SE 配置中不对称电源的设计。一个缓冲器用于 HVPREF(引脚 11)上的参考
去耦电容器 (CHVPREF),另外两个缓冲器用于与扬声器串联的两个交流耦合电容器 (CSE)
说明
-
Simplified application circuit of the TDA8933B device when operated from an asymmetrical supply (single supply). The TDA8933B incorporates three integrated half supply voltage buffers to simplify the design for an asymmetrical supply in SE configuration. One buffer is for the reference decoupling capacitor (CHVPREF) on HVPREF (pin 11) and two other buffers are for the two AC-couple capacitors (CSE) in series with the speaker
