Hi, Ben,
The TPA2000D1-Q1 is able to reach 1W with an 8ohms load as shown in the electrical characteristics:

I would suggest to use a VDD = 5V, set the gain to 23.5dB and use an input signal of 200mV amplitude. This should be enough to reach the 1W output.

hi
TPA2000D1-Q1 and TPA2001D1 are pin to pin? Can I use TPA2001D1 to make 0.5W/8 ohm SPK? How to set?
Hi, Ben,
Yes, the TPA2000D1-Q1 and TPA2001D1 are pin to pin compatible.
In order to set an output gain of 0.5W with an 8ohms load, it is important to consider that the output depends of the input signal and the selected gain. For a 0.5W output, you will require an output voltage of 2Vrms. So, you would need to have one of these combinations:
