TFA9882 direct drive of loudspeaker

408***361

2020-09-30 03:10

We have designed the NXP TFA9882 into consumer audio conferencing station, but are having trouble with high noise level on the speaker output. We want to get application notes or application advice on how to get a much better sound quality when this class D filter-less amplifier is driving a small 4ohm impedance loudspeaker. The noise we see on a 1KHz sine wave output includes both bad harmonics at 2,3,4,5,6,7 KHz and a high noise floor - 12dB higher than the same signal through a standard laptop speaker.
