Product Details

The DC2873A-B and the DC2873A-C, hereafter referred to as the DC2873A, are fully featured evaluation boards used to evaluate the LTC2688, a 16-channel, 16-bit or 12-bit precision voltage output digital-to-analog converter (DAC).

The DC2873A-B is populated with the 16-bit version of the LTC2688 (LTC2688-16), and the DC2873A-C (LTC2688-12) is populated with the 12-bit version of the LTC2688.

The DC2873A 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 DC2873A.

The DC2873A uses Analysis, Control, Evaluation (ACE) software to provide an intuitive graphical user interface (GUI) that configures and controls the LTC2688 using the SPI interface.

The LTC2688 is used for various voltage mode biasing applications such as optical modulators for data communications. The output voltage range for each channel is software selectable, and any channel can be routed to the DC2873A MUX pin, allowing either the channel voltage or current to be externally monitored.

For full specifications on the LTC2688-16 and LTC2688-12, see the LTC2688 data sheet, which must be consulted in conjunction with the user guide when using the DC2873A.
