In the figure we have an audio amplifier suitable for portable applications in both mono and stereo (BTL) versions. The diagram shown is for the stereo version, but in the original Holtek documentation that manufactures the HT82V732, the integrated circuit used in the project, the bridge application can be found. The integrated circuit is supplied in an 8-pin SOP enclosure. The pass-through range is 20 kHz and the gain without feedback is 70 dB.
