Other Parts Discussed in Thread: TPA2012D2
According to the efficiency of TPA2012D2 of Figure 31 on the datasheet, it seems to be around >85% under the condition of Vdd=5V, 1W output and 8 ohm load.
When I measured it by using EVM under the same condition, the results shows about only 80%.
Why is there differences between EVM and datasheet?
Of course I placed a 33uH inductor in series with the load resistor and also using LPF (1k ohm and 4700pF).
