The VCA2617 is a dual-channel, continuously variable, voltage-controlled amplifier. The VCA2617EVM evaluation module is designed to allow for a quick setup and ease of use in evaluating the performance. Various modes of operation can be configured, for example using the transfomer coupled, or the direct single-ended input mode. The differential outputs of the VCA2617 are buffered using an op amp in a difference amplifier configuration.
The VCA2617EVM requires a +5 V supply for the VCA itself, and +/-5 V supplies for the buffer amplifiers. All signal inputs and outputs use SMA connectors.
