THS4304

SLOS436A – MARCH 2004 – REVISED JULY 2004

APPLICATION INFORMATION (continued)

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.

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.
