Simple PC Data Acquisition by AD7569
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
