  2. Offset binary - Wikipedia

    en.wikipedia.org/wiki/Offset_binary

    A simple solution to this is to bias the analog signals with a DC offset equal to half of the A/D and D/A converter's range. The resulting digital data then ends up being in offset binary format. [5] Most standard computer CPU chips cannot handle the offset binary format directly [citation needed]. CPU chips typically can only handle signed and ...

    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 ...

  4. Successive-approximation ADC - Wikipedia

    en.wikipedia.org/wiki/Successive-approximation_ADC

    Counter type ADC: The D to A converter can be easily turned around to provide the inverse function A to D conversion. The principle is to adjust the DAC's input code until the DAC's output comes within ± 1 ⁄ 2 LSB to the analog input which is to be converted to binary digital form. Servo tracking ADC: It is an improved version of a counting ...

  5. 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.

  6. Integral nonlinearity - Wikipedia

    en.wikipedia.org/wiki/Integral_nonlinearity

    In ADCs, it is the deviation between the ideal input threshold value and the measured threshold level of a certain output code. This measurement is performed after offset and gain errors have been compensated. [1] The ideal transfer function of a DAC or ADC is a straight line. The INL measurement depends on what line is chosen as ideal.

  7. Effective number of bits - Wikipedia

    en.wikipedia.org/wiki/Effective_number_of_bits

    Effective number of bits (ENOB) is a measure of the real dynamic range of an analog-to-digital converter (ADC), digital-to-analog converter (DAC), or associated circuitry. . Although the resolution of a converter may be specified by the number of bits used to represent the analog value, real circuits however are imperfect and introduce additional noise and distor

  8. Signed number representations - Wikipedia

    en.wikipedia.org/wiki/Signed_number_representations

    In the offset binary representation, also called excess-K or biased, a signed number is represented by the bit pattern corresponding to the unsigned number plus K, with K being the biasing value or offset. Thus 0 is represented by K, and −K is represented by an all-zero bit pattern.

  9. Signal conditioning - Wikipedia

    en.wikipedia.org/wiki/Signal_conditioning

    In an analog-to-digital converter (ADC) application, signal conditioning includes voltage or current limiting and anti-aliasing filtering. In control engineering applications, it is common to have a sensing stage (which consists of a sensor ), a signal conditioning stage (where usually amplification of the signal is done) and a processing stage ...
