APPLICATION INFORMATION (continued)
SOT-23 versus MSOP
With light loading of 500-Ω and higher resistance, the THS4304 shows HD2 that is not dependant of package.
With heavy output loading of 100 Ω, the THS4304 in SOT-23 package shows about 6 dB better HD2
performance versus the MSOP package.
EVALUATION MODULES
The THS4304 has two evaluation modules (EVMs) available. One is for the MSOP (DGK) package and the other
for the SOT-23 (DBV) package. These provide a convenient platform for evaluating the performance of the part
and building various different circuits. The full schematics, board layout, and bill of materials (as supplied) for the
boards are shown in the following illustrations.
