APPLICATION INFORMATION

evaluation board

An evaluation board is available for the THS4011 (literature number SLOP128) and THS4012 (literature number

SLOP230). This board has been configured for very low parasitic capacitance in order to realize the full

performance of the amplifier. A schematic of the THS4011 evaluation board is shown in Figure 40. The circuitry

has been designed so that the amplifier may be used in either an inverting or noninverting configuration. For

more information, please refer to the

THS4011 EVM User’s Guide (literature number SLOU028) or the THS4012

EVM User’s Guide (literature number SLOU041) To order the evaluation board contact your local TI sales office

or distributor.
