GPM8903 Non-Clip,Low EMI Audio Class D Amplifier General Description The GPM8903 is a Class D amplifiers provide high performance, thermally efficient amplifier solutions. The GPM8903 delivers 1*4.5W into a 2 Ω load. An integrated limiting circuit prevents output clipping distortion, that makes GPM8903 has excellent sound reproduction and protects small speakers from transient volt-ages, reduces power dissipation. The GPM8903 has a 2:1 input MUX for audio source selection. The MUX was selected by an external pin. Both input channels have a 32-step Up/Down volume control. Filter-less modulation allows the IC to pass EMI limits with 1m cables using only a low-cost ferritebead and small-value capacitor on each output.
