DAC8: Octal 8-bit Digital-to-Analog Converter
The octal 8-bit DAC card (DAC8) uses the TI DAC088S to give eight channels of 8-bit digital to analog conversion. You can select either 3.3 or 5 volts as the maximum.
Hardware:The schematic and layout of the DAC8 are shown below. The Eagle schematic and board files are available here: dac8.sch and dac8.brd. The bill-of-materials is contained here: dac8.txt
The board layout is shown below. The header for selecting the maximum output voltage (Vo) is in lower left. Select a 5 volt maximum output by placing the jumper from the Vo pin to the pin labeled 5, and select 3.3 volt output by placing the jumper from Vo to the pin labeled 3. Immediately above the output selection jumper is a header that provides 5 volts, 3.3 volts, and ground. You can use this header to power any circuits you build in the prototyping area.
