The VCA2618 is a dual, variable gain amplifier with a 45dB gain range. The VCA2618EVM evaluation module comes as a completely assembled board ready to evaluate the VCA2618 in its various modes. The input signal is applied in single-ended form, while the differential outputs of the VCA2618 are buffered using an opamp in a difference amplifier configuration. This amplifier is also capable of driving a terminated 50 ohm load, suitable for lab test equipment. Switches allow to operate the VCA2618 in all possible configurations.
The VCA2618EVM requires a +5V supply for the VCA2618 itself, and an additional +/-5V for the output buffer amplifier. All signal inputs and outputs use SMA connectors
