R/2nR DAC This R/2nR DAC circuit, otherwise known as the binary-weighted-input DAC, is a variation on the inverting summer op-amp circuit.…
An alternative to the binary-weighted-input DAC is the so-called R/2R DAC, which uses fewer unique resistor values. R/2R DAC versus…
Flash ADC also called the parallel A/D converter, this circuit is the simplest to understand. It is formed of a series…
A third variation (Tracking ADC) on the counter-DAC-based converter theme is, in my estimation, the most elegant. Instead of a…
So far, we\'ve only been able to escape the sheer volume of components in the flash converter by using a…
One of the more advanced ADC technologies is the so-called delta-sigma, or ΔΣ (using the proper Greek letter notation). In…
Perhaps the most important consideration of an ADC is its resolution. Resolution is the number of binary bits output by the…
Connecting digital circuitry to sensor devices is simple if the sensor devices are inherently digital themselves. Switches, relays, and encoders…
Digital Ramp Analog to Digital Converter (ADC) also known as the stair-step-ramp, or simply counter A/D converter, this is also fairly easy…
One method of addressing the digital ramp ADC's shortcomings is the so-called successive-approximation ADC. The only change in this design is…
