TDA8932B D Audio Amplifier

Posted on Feb 7, 2014

The following circuit diagram is a simplified application circuit of the TDA8932B/33(B) device when operated from an asymmetrical supply (single supply). Here`s the circuit diagram: To simplify the design for an asymmetrical supply in SE configuration, the TDA8932B/33(B) is equipped with three integrated half supply voltages buffers. The first buf
