Product Details

The DC2903A is a fully featured evaluation board that evaluates the LTC2672, a five-channel, current source output digital-to-analog converter (DAC).

The DC2903A is controlled through a serial peripheral interface (SPI) from the J1 connector. The SPI signals are sent from the DC2026C controller board through the ribbon cable that is connected to the DC2903A.

The DC2903A uses QuikEval evaluation software to provide an intuitive graphical user interface (GUI) that configures and controls the LTC2672 using the SPI interface.

The LTC2672 is used for various current mode biasing applications such as tunable lasers or resistive heaters. The output current ranges are software selectable, and each channel is routed to the DC2903A MUX pin for external monitoring.

For full specifications on the LTC2672, see the LTC2672 data sheet, which must be consulted in conjunction with the DC2903A user guide when using the DC2903A.
