Analog-to-digital converter (ADC) chips transform information from analog to digital form

Digital-to-analog converters (DAC) transform a digital number into a corresponding analog voltage or current

Digital-to-analog converter (DAC) chips convert digital signals that represent binary numbers into proportional analog voltages

Frequency-to-voltage converters accept a signal and convert its frequency to a corresponding analog voltage level

Scan and video converters transform a digital computer image to a standard video signal for use with broadcasting or video devices such as televisions, monitors, or VCRs or vice versa

Power supplies are devices that produce AC or DC power.

Data acquisition computer boards are self-contained printed circuit boards that typically plug into the backplane, motherboard, or otherwise interface directly with the computer bus.
