|AIU - Analog Interface Unit|
If you need to add simple data acquisition capabilities to your PC, then look no further than the Analog Interface Unit.
The Analog Interface Unit (AIU) is a simple circuit that connects to a PC parallel port, and allows you to sample and output 8-bit analog signals under software control.
Here are some of the features :
- 8-bit ADC and DAC
- Powered from the parallel port
- 1Mohm input impeadance.
- Software selectable +/-1.25V or +/-2.5V input and output ranges.
I'm making the all of the details of this project available for FREE downloading for individual construction, but I'm still keeping copyright on the design and included software. It is NOT Public Domain.
