Hello all,
With my current project I am working on, I have a TPA2013D that is being powered from a single Li-Ion battery, hooked up to a 4 ohm speaker. I want to add a TLV320DAC3203 to it, to offer some local EQ settings, and to keep the analog potion to a minimum. I am getting stuck on what I should do about powering both of them. I do have a couple ideas;
1) Use the boost converter of the TPA2013D, that is set to 5.5V, to power both the class-D amp, and the TVL320DAC3203. I would be using a 3.3V LDO, and a 1.8V LDO for the DAC power.
2) design a separate 5.5V boost converter to power both the class-D amp, and LDOs for the DAC.
I am trying to keep things simple as possible.
Does anyone have an idea on what would be my best option? I am not looking to save cost, but I am worried about space. I dont have that much room to work with. And I am also worried about sound quality.
Thanks
Anthony
