APPLICATION INFORMATION

evaluation board

An evaluation board is available for the THS4081 (literature number SLOP242) and THS4082 (literature number

SLOP239). 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 51. 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 THS4081 EVM User’s Guide or the THS4082 EVM User’s Guide. To order the

evaluation board, contact your local TI sales office or distributor.
