DAC's or Digital to Analog Converters are used to convert digital data, typically binary, into an analog signal such as a current, voltage, or electrical charge. ADC's or Analog to Digital Converters are used to convert analog signals like voltage into a digital number that represents the quantities amplitude. PWM's or Pulse Width Modulators are devices that vary the width of the pulse based on modular signal information. Their main use includes allowing the control of the power supplied to electrical devices. Listed on this page are devices used for control and processing of digital and analog data. They can be used in a wide array of devices to include solid state and computer electronics.
