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.


- TI DAC088S
- Eight channels of 8 bit conversion
- Uses the ESPI 7474 circuit for reliable operation
- Maximum output can be either 3.3 or 5 volts



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.
