The VCA2619 is a dual, variable gain amplifier with a 50dB gain range, low noise, low crosstalk and distortion. The VCA2619EVM evaluation module comes as a completely assembeled board ready for the user to evaluate the VCA2619 in it various modes. The input signal is applied in single-ended form, while the differential outputs of the VCA2619 are buffered using an opamp in a difference amplifier configuration. This amplifier is capable of driving a terminated 50ohm load, suitable for lab test equipment. The installed switches allow the user to operate the VCA2619 in all possible configurations.
The VCA2619EVM requires a +5V supply for the VCA2619 itself, and an additional +/-5V for the output buffer opamps. All signal inputs and outputs use SMA connectors
