Texas Instruments DEM-FDA-SOIC-EVM Amplifier Evaluation Module

Texas Instruments DEM-FDA-SOIC-EVM Amplifier Evaluation Module (EVM) is an unpopulated evaluation module for fully differential amplifiers (FDA) in the D (SOIC) package. This evaluation module is designed in accordance with high-speed performance specifications and Texas Instruments FDAs with output common-mode (Vocm) control and power down (PD) functionality. The evaluation module enables quick and efficient lab testing of the high-speed FDAs using 50Ω SMA connectors for use with lab equipment. The schematic considers all necessary connectors, including power and signal connections, to perform lab measurements. The evaluation module is configured for single-ended input and single-ended output when populated according to the schematic; the evaluation module can accommodate fully differential behavior with proper configuration. The output transformer enables single-ended output for easy interfacing with test equipment, and there are external SMA connectors for output common-mode and power-down control. Additional options on the amplifier input traces prior to termination resistors and extensions of transformer pads after the amplifier outputs allow for optional AC coupling.
