Hello,
We are designing a board with several amplifiers chips. Currently we are using TAS5716 in SE mode and we'd like to move to BTL mode but the problem is our speakers are 4ohm so we cannot use TAS5716 any more and we wold have to move to other chips like TAS5713 or TAS5717/9. There are plenty of electrical information in the TAS5716 datasheet but barely nothing in the rest. In order to know the power supply needed to feed this board we need to know the supply current vs output power but let's do it one by one:
- TAS5713: THND vs Freq for 4ohm BTL avaiable but only for 12 & 18V PVDD, is it possible to use 24V? which would be the THND vs Freq? Also cannot find the following information: supply current vs output power , efficiency vs PVDD and Power for 4ohm BTL
- TAS5717/ TAS5719: Only displaying 8ohm BTL info. Needed same graphs for 4ohm BTL; supply current vs output power , efficiency vs PVDD and supply current vs output.
I'd really appreciate this information, most important current supply vs output power because of the Power supply choosing. Thanks in advance and have a nice day!
Adrian
