Analog Interface Card - A2D2A for Texas Instruments DSP Development Systems
The design of an interface card with eight analog inputs and four analog outputs is described in this technical paper. The standards stipulated in Texas Instruments TMS320 Cross-Platform Daughtercard Specification, Revision 1.0, [1] have been followed in the design process. This card can be used with any Texas Instruments TI320 DSP development system. The A2D2A generates all of the necessary voltages on board from the 5V power, which is available according to the TMS320 Cross-Platform Daughtercard Specifications. For an easy interface, the common BNC coaxial connectors are used for the input and output connections. To reduce the manufacturing costs, the card has been designed using a two layer PCB.
