TPA2028D1 / Output Limiter Level (Address: 6)

Other Parts Discussed in Thread: TPA2028D1

Hi Team,

I would like to ask a simple question.
Can I limit output power of TPA2028D1 to 0.79Wrms if I only set REG06 register (AGC Control) =1D?

I believe it but my customer said he coudn't limit output power to 0.79Wrms.
Is there any concern?

I also put all register values as the following.
----------------------------------------
REG01=C3
REG02=05
REG03=0B
REG04=00
REG05=00
REG06=1D
REG07=00
----------------------------------------
