APPLICATION INFORMATION
For example, if the 5-V supply is replaced with a 3.3-V supply (TPA0102 has a maximum recommended VDD
of 5.5 V) in the calculations of Table 1, then efficiency at 0.5 W would rise from 44% to 67% and internal power
dissipation would fall from 0.62 W to 0.25 W at 5 V. Then for a stereo 0.5-W system from a 3.3-V supply, the
maximum draw would only be 1.5 W as compared to 2.24 W from 5 V. In other words, use the efficiency analysis
to chose the correct supply voltage and speaker impedance for the application.
