2. Analog-to-digital converter - Wikipedia

   en.wikipedia.org/wiki/Analog-to-digital_converter

   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. 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).

4. Delta-sigma modulation - Wikipedia

   en.wikipedia.org/wiki/Delta-sigma_modulation

   Delta-sigma (ΔΣ; or sigma-delta, ΣΔ) modulation is an oversampling method for encoding signals into low bit depth digital signals at a very high sample-frequency as part of the process of delta-sigma analog-to-digital converters (ADCs) and digital-to-analog converters (DACs).

5. Mixed-signal integrated circuit - Wikipedia

   en.wikipedia.org/wiki/Mixed-signal_integrated...

   Mixed-signal ICs contain both digital and analog circuitry on the same chip, and sometimes embedded software. Mixed-signal ICs process both analog and digital signals together. For example, an analog-to-digital converter (ADC) is a typical mixed-signal circuit.

6. 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 ...

7. 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 ...

8. Digital-to-analog converter - Wikipedia

   en.wikipedia.org/wiki/Digital-to-analog_converter

   An analog-to-digital converter (ADC) performs the reverse function. There are several DAC architectures; the suitability of a DAC for a particular application is determined by figures of merit including: resolution, maximum sampling frequency and others. Digital-to-analog conversion can degrade a signal, so a DAC should be specified that has ...

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 ...
