2.65W CLASS-D AUDIO POWER AMPLIFIER
Bead and Capacitor
The A2323 under lacking bead, capacitor condition, for 60cm audio cable, still can meet FCC standard. For
lengthen audio output signal route and component near EMI sensitive device, design with bead, capacitor is
recommended. The placement of bead and capacitor must as near as possible.
Figure 6 Bead and Capacitor
Bead Recommend Type
The A2323 as class-D power amplifier, output square wave signal, this square wave signal creating switching
current under output filter capacitor, causing static power consumption, so bigger output filter capacitance not
recommended, design with 1nF ceramic capacitor is recommended.
FC Package
The A2323 provide tiny 1.5mm X 1.5mm FC-9 package. The FC package base on advance Flip-Chip
packaging technology, copper plated silver frame (Cu/Ag), Package pad with tin plated layer thickness
between 0.03~0.05mm, capable of mature stable packaging reliability, it has been guaranty the surface
mount process Yield rate.
