APPLICATION INFORMATION
circuit layout considerations (continued)
Surface-mount passive components – Using surface mount passive components is recommended for high
frequency amplifier circuits for several reasons. First, because of the extremely low lead inductance of
surface-mount components, the problem with stray series inductance is greatly reduced. Second, the small
size of surface-mount components naturally leads to a more compact layout thereby minimizing both stray
inductance and capacitance. If leaded components are used, it is recommended that the lead lengths be
kept as short as possible.
evaluation board
An evaluation board is available for the THS4001 (literature number SLOP119). This board has been configured
for very low parasitic capacitance in order to realize the full performance of the amplifier. A schematic of the
evaluation board is shown in Figure 23. The circuitry has been designed so that the amplifier may be used in
either an inverting or noninverting configuration. To order the evaluation board contact your local TI sales office
or distributor. For more detailed information, refer to the THS4001 EVM User’s Manual(literature number
SLOU017).
