Description

The DEM-FDA-RUN-EVM is an evaluation module for RUN package (WQFN 10-pin) fully-differential amplifiers (FDAs), supporting multiple high-speed FDAs. This board supports quick demonstration of functionality and capability, including the SMA connectors for ease of use and supporting multiple onboard configurable options: MFB active filter, load network to FDA, output transformer, external drive for power down and output common-mode voltage. The EVM uses banana connectors for power supply, interfacing with bench power supplies. The supply voltage range is customizable depending on FDA selection and passive component choices. By default the partially assembled EVM is configured for 2.7V to 5.5V supplies. The input & output SMAs are 50Ω-matched for interfacing with common lab equipment. One jumper is available to select between power down modes, which can be bypassed for externally driven power sequencing.
