Introduction and Description
The Texas Instruments THS4140 evaluation module (EVM) helps designers
evaluate the performance of the THS4140 operational amplifier. Also, this
EVM is a good example of high-speed PCB design.
This document details the Texas Instruments THS4140 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 THS4140 EVM.
