Other Parts Discussed in Thread: TLV320DAC3120
There is a good news that we design in TPA3111D1 in customer's new project.
In this condition, what is the value of output power?
As stated in your schematic, the gain is 20dB or 10V/V. With 1Vrms in, the output will be 10Vrms. With a 12V supply, one cannot get to 10Vrms without clipping. To calculate the power with losses, look at section 7.3.4 in the datasheet for the details.
The preliminary setting for TPA3111D1PWPR is below, due to the minimum gain setting is 20dB, so we would need an Attenuator before INP input, then fine tune it to our target power 5~8W, if the INP input is 1Vrms that output will be clipped from comments.
