1 Introduction

The DEM-OPA-RGV-EVM is an unpopulated evaluation module (EVM) for TI's dual, wideband operational amplifiers in the VQFN (RGV) package. This EVM is designed in accordance with high-speed performance specifications and Texas Instruments' PLC and Transmission Line Drivers. The EVM is designed to enable quick and efficient lab testing of TI High Speed dual amplifier using 50-Ω SMA connectors for use with lab equipment. The EVM can be easily configured for different gains and for single or split-supply operation. The two channels can be used as individual amplifiers or can be configured as a differential-input to differential-output driver. A transformer with appropriate resistors can be used at the output as a 50-Ω single-ended output.
