Figure 33. Application Schematic With TPA2031D1 Summing Two Single-Ended Inputs
In making the pad size for the WCSP balls, it is recommended that the layout use non-solder-mask-defined
(NSMD) land. With this method, the solder mask opening is made larger than the desired land area, and the
opening size is defined by the copper pad width. Figure 34 and Table 2 show the appropriate diameters for a
WCSP layout. The TPA2031D1 evaluation module (EVM) layout is shown in the next section as a layout
example.
