Introduction and Description

The Texas Instruments THS4151 evaluation module (EVM) helps designers evaluate the performance of the THS4151 operational amplifier. Also, this EVM is a good example of high-speed PCB design.

This document details the Texas Instruments THS4151 high-speed operational amplifier evaluation module (EVM). It includes a list of EVM features, a brief description of the module illustrated with a series of schematic diagrams, EVM specifications, details on connecting and using the EVM, and a discussion of high-speed amplifier design considerations.

This EVM enables the user to implement various circuits to clarify the available configurations presented by the schematic of the EVM. In addition, the schematic of the default circuit has been added to depict the components mounted on the EVM when it is received by the customer. This configuration correlates to the single input/differential output signal.

Other sample circuits are presented to show how the user can implement other circuit configurations such as differential input/differential output signal, transformer utilization on the input and output terminals, VICR level shifter, and Butterworth filter with multiple feedback. The user may be able to create and implement circuit configurations in addition to those presented in this document using the THS4151 EVM.
