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 impedance.
* Software selectable +/-1.25V or +/-2.5V input and output ranges.
