The OPA857EVM is an evaluation module for the OPA857 amplifier in a QFN-16 (RGT) package. This evaluation module is designed to quickly and easily demonstrate the functionality and versatility of the amplifier. The EVM is ready to connect to power, signal source, and test instruments through the use of onboard connectors. The EVM comes configured for easy connection with common 50-Ω laboratory equipment on its inputs and outputs. The amplifier is configured for a single-ended input with a selectable transimpedance gain (5kΩ/20kΩ). The pseudo-differential output at the device pins is then converted to a single-ended signal through an RF transformer.
