About This Manual

This manual is written to provide information about the evaluation module of the fully differential amplifier under test. Additionally, this document provides a good example of PCB design for high speed applications. The user should keep in mind the following points.

The design of the high-speed amplifier PCB is an elegant and sensitive process. Therefore, the user must approach the PCB design with care and awareness. It is recommend that the user initially review the datasheet of the device under test. It is also helpful to review the schematic and layout of the THS4130 EVM to determine the design techniques used in the evaluation board. In addition, it is recommended that the user review the application note Fully-Differential Amplifiers (literature number SLOA054B) to gain more insight about differential amplifiers. This application note reviews the differential amplifiers and presents calculations for various filters.
