Hi,
The gain depends on the power supply voltage since the open loop system has been adopted to TAS5352A.
Unfortunately, we do not have TAS5352A evm although we would like to evaluate that characteristic.
Then, could you please send us the graph of "the gain vs the power supply voltage" in the unclipped power output?
The condition is shown as below.
Pout : 5W ~ 70W(the unclipped output voltage)
Rload : 4Ω, 6Ω
PVDD_X : 12V ~ 36V
Output Configuration : BTL
Best Regards,
Kato
