TPA3113D2 / Minimum Load Resistance

Guru 29720 points

Other Parts Discussed in Thread: TPA3113D2, TPA3118D2

Hi Team,

My customer considers to use 4Ω±0.5Ω speaker(stereo, BTL) with TPA3113D2 under PVDD=19V.
However Abs max rating of the datasheet shows "Minimum Load Resistance" is 4.8Ω under this condition.

Should my customer use more than 4.8Ω speaker even though setting power limit (PLIMIT)?
He considers to set power limit around 4W/ch each.



Best Regards,
Yaita
