    4-channel stereo multiplexed analog-to-digital converter WM8775SEDS made by Wolfson Microelectronics placed on an X-Fi Fatal1ty Pro sound card AD570 8-bit successive-approximation analog-to-digital converter AD570/AD571 silicon die INTERSIL ICL7107. 3.5 digit (i.e. conversion from analog to a numeric range of 0 to 1999 vs. 3 digit range of 0 to 999, typically used in meters, counters, etc ...

  3. Flash ADC - Wikipedia

    en.wikipedia.org/wiki/Flash_ADC

    A flash ADC (also known as a direct-conversion ADC) is a type of analog-to-digital converter that uses a linear voltage ladder with a comparator at each "rung" of the ladder to compare the input voltage to successive reference voltages.

  4. Successive-approximation ADC - Wikipedia

    en.wikipedia.org/wiki/Successive-approximation_ADC

    Example 1: The steps to converting an analog input to 9-bit digital, using successive-approximation, are shown here for all voltages from 5 V to 0 V in 0.1 V iterations. Since the reference voltage is 5 V, when the input voltage is also 5 V, all bits are set.

  5. Integrating ADC - Wikipedia

    en.wikipedia.org/wiki/Integrating_ADC

    An integrating ADC is a type of analog-to-digital converter that converts an unknown input voltage into a digital representation through the use of an integrator.In its basic implementation, the dual-slope converter, the unknown input voltage is applied to the input of the integrator and allowed to ramp for a fixed time period (the run-up period).

  6. Data acquisition - Wikipedia

    en.wikipedia.org/wiki/Data_acquisition

    Data acquisition is the process of sampling signals that measure real-world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems, abbreviated by the acronyms DAS, DAQ, or DAU, typically convert analog waveforms into digital values for processing. The ...

  7. Delta modulation - Wikipedia

    en.wikipedia.org/wiki/Delta_modulation

    Rather than quantizing the value of the input analog waveform, delta modulation quantizes the difference between the input signal and the integral of all previous quantization steps. This quantized signal effectively represents the derivative of the input signal, [ 1 ] [ 2 ] so the original signal is recovered by integration, as shown in the ...

  8. Modulation - Wikipedia

    en.wikipedia.org/wiki/Modulation

    Digital modulation methods can be considered as digital-to-analog conversion and the corresponding demodulation or detection as analog-to-digital conversion. The changes in the carrier signal are chosen from a finite number of M alternative symbols (the modulation alphabet ).

  9. Analog signal to discrete time interval converter - Wikipedia

    en.wikipedia.org/wiki/Analog_signal_to_discrete...

    An analog signal to discrete time interval converter (ASDTIC) is a specialized kind of an analog-to-digital converter, which converts the analog input signal (e.g. voltage or current) to time intervals between pulses. This conversion is a type of Pulse-width modulation (PWM). The origin of the term ASDTIC lies with NASA around 1970. [1]
