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).

In dual slope type ADC, the integrator generates two different ramps, one with the known analog input voltage VA and another with a known reference voltage –Vref. Hence it is called a s dual slope A to D converter.

A dual slope ADC is preferable to a single slope analog-to-digital converter. For a clear conception of the dual-slope ADC, we will study the single slope ADC first. It consists of an integrator and a comparator.

An answer to this calibration drift dilemma is found in a design variation called the dual-slope converter. In the dual-slope converter, an integrator circuit is driven positive and negative in alternating cycles to ramp down and then up, rather than being reset to …

Introduced in the 1950s, the "dual-slope" ADC architecture was truly a breakthrough in ADCs for high resolution applications such as digital voltmeters, etc. (see References 1-4). A simplified diagram is shown in Figure 1, and the integrator output waveforms are shown in Figure 2. OSC.

2021年7月9日 · There are two types of slope ADCs such as single slope and dual slope. An slope type 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.

Abstract: With dual-slope integrating analog-to-digital (A/D) converters, which are most frequently used for relatively low-speed conversion, the drift of the operational amplifier is a very critical factor in limiting their performance.

2021年6月4日 · This Tutorial describes two basic implementations of integrating analog to digital converters, the dual slope and the charge balancing converter, as well as the basic process and the...

The Single- and Dual-slope Analog to Digital Converters Summary. We now consider the single-slope and the dual-slope ADCs. Both ADCs make use of simple op-amp circuits and control logic to do most of their work. We explain why the slightly more complicated dual-slope ADC is generally a better choice of ADC than the single-slope converter.

The Dual Slope ADC (Analog-to-Digital Converter) is a popular method used to convert an analog signal into its corresponding digital value. It is particularly favoured for its accuracy, low noise sensitivity, and simplicity in many applications requiring precision measurements.
