The VCA2614 is a dual, variable gain amplifier with a 40dB gain range. The VCA2614EVM evaluation module comes as a completely assembled board ready to evaluate the VCA2614 in its various modes. The input signal is applied in single-ended form, while the differential outputs of the VCA2614 are buffered using an opamp in a difference amplifier configuration. This amplifier is also capable of driving a terminated 50ohm load, suitable for lab test equipment. Switches allow the user to operate the VCA2614 in all possible configurations.
The VCA2614EVM requires a +5V supply for the VCA2614 itself, and an additional +/-5V for the output buffer opamps. All signal inputs and outputs use SMA connectors.
