說明
-
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
