The VCA2612 is a dual, variable gain amplifier including a low-noise preamplifier (LNP). The VCA2612EVM evaluation module is designed to provide a complete evaluation platform for the VCA2612. The user can apply the input signal either to the LNP, or directly to the VCA section. The differential outputs of the VCA2612 are buffered using an op amp in a difference amplifier configuration. This amplifier is also capable of driving a terminated 50ohm load, suitable for lab test equipment. The installed switches allow the user to operate the VCA2612 in all possible configurations.
The VCA2612EVM requires a +5V supply for the VCA2612 itself, and an additional +/-5V for the output buffer opamps. All signal inputs and outputs use SMA connectors
