DEM-OPA-WSON8-EVM

User's Guide SBOU214 – September 2018 DEM-OPA-WSON8-EVM The DEM-OPA-WSON8-EVM is an unpopulated evaluation module for the single channel op-amps in the DSG (8-pin WSON) package. This EVM is designed to high-speed performance specifications and is compatible with amplifiers that have over 1 GHz of gain bandwidth. 1 Features • • • • 2 Configured for split-supply operation and modified for single-supply Configurable for inverting and noninverting gain configurations Includes connections for termination resistors to match to standard 50-Ω input/output impedance test equipment Inputs and outputs use standard SMA connector footprints EVM Specifications This section provides a general description of the DEM-OPA-WSON8-EVM. 2.1 Power Connections The DEM-OPA-WSON8-EVM is designed to use banana jacks for easy connection of power. The positive supply input is labeled VCC, the negative supply input is labeled VEE, and ground is labeled GND. 2.1.1 Split-Supply Operation To operate in split-supply, apply the positive supply voltage to VCC, the negative supply voltage to VEE, and the ground reference from supply to GND. 2.1.2 Single-Supply Operation To operate in single-supply, apply jumper VEE to GND and apply the positive supply voltage to VCC. Inputs and outputs must be biased based on your selected device data sheet specifications for proper operation. 2.2 Input and Output Connections The DEM-OPA-WSON8-EVM is equipped with footprints for SMA connectors to connect to signal generators and analysis equipment. Typically test equipment has 50-Ω termination, so matching resistors R1 and R3 are provided to create matched impedances in any configuration. For best results, signals must be routed to and from the EVM with cables with a characteristic impedance of the same value as the test equipment and board. 3 EVM Schematic, Layout, and Bill of Materials (BOM) This section provides a complete schematic diagram, board layouts, and bill of materials for the DEMOPA-WSON8-EVM.
