Application Information GENERAL AMPLIFIER FUNCTION The LM48413 stereo Class D audio power amplifier features a filterless modulation scheme that reduces external compo- nent count, conserving board space and reducing system cost. The outputs of the device transition from PV with ...
Page 11
The 3D RC network acts as a high-pass filter. The amount of the 3D effect is set by the R resistor. Decreasing the value 3D of R3D increases the 3D effect. The C frequency at which the 3D effect occurs. ...

AUDIO AMPLIFIER GAIN The LM48413 has a fix gain value 24dB which is suitable for ordinary audio applications. To reduce the amplifier gain, in- sert two pairs of external input resistors with same value before the IC’s input signal pins. ...
