... SOIC package. The thermal resistance is obtained with the EL1508CL and CS demo boards. The demo board is a 4-layer board built with 2oz. copper and has a dimension of 4in guideline to achieve these results. In addition to lower thermal resistance, the QFN package exhibits much lower 2nd harmonic distortion ...
