Other Parts Discussed in Thread: TAS5805M, , TAS5805
Dear colleagues,
I am working on a smart speaker project with this main requirement:
- 2.1 audio system - 4Ohms speaker - 2*20W+ 30W up to 2*25W + 40W / or any combination that doesnt exceed 90W in total and that remains compliant with amplifier output drive.
- Battery inside - so far the architecture is wrapped around 3S2P li-ion battery
- USB-PD
- Wireless phone charger in option
Current version of the power supply architecture is the following:
Any thought on it ? Recommandation ?
In the amplifier datasheet (TAS5711 / TAS5805M) we see that they are wide input voltage. Theoretically they can stand the swing from 20V (USB-PD wall charger) to 9V (battery discharged) so is it OK to power the amp directly connected to VSYS ? Will it be able to drive the same output power in both case ? (i think not but i prefer to ask).
About the amp, during market analysis i found the TAS5711 used in quite a good product, but it is getting old (almost 10 years). TAS5805M is more recent with similar spec.
Which amplifier would you recommend for this project ?
Feel free to add any suggestions and advices !
Thanks & regards,
Samir
