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. The logic diagram for the same is shown below.

Dual Slope ADC. As the name suggests, a dual slope ADC produces an equivalent digital output for a corresponding analog input by using two (dual) slope technique. The block diagram of a dual slope ADC is shown in the following figure −. The dual slope ADC mainly consists of 5 blocks: Integrator, Comparator, Clock signal generator, Control ...

Enhanced run-up dual-slope integrating ADC. The run-up phase of the basic dual-slope design integrates the input voltage for a fixed period of time. That is, it allows an unknown amount of charge to build up on the integrator's capacitor. The run-down phase is then used to measure this unknown charge to determine the unknown voltage.

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.

Jul 9, 2021 · 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.

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.

A dual-slope ADC (DS-ADC) integrates an unknown input voltage (V IN) for a fixed amount of time (T INT), then "de-integrates" (T DEINT) using a known reference voltage (V REF) for a variable amount of time (see Figure 2).

Feb 18, 2025 · Dual slope ADCs. Dual slope ADCs are accurate but not terribly fast. The principal way they convert analog to digital values is by using an integrator. The voltage is input and allowed to “run up” for a period of time. Then a known voltage of the opposite polarity is applied and allowed to run back down to zero.

A dual-slope ADC, on the other hand, averages together all the spikes and dips within the integration period, thus providing an output with greater noise immunity. Dual-slope ADCs are used in applications demanding high accuracy.

What is Dual Slope ADC? A Dual Slope ADC is a type of integrating ADC that converts an analog signal into a digital value by integrating the input signal over a fixed time period and then performing a counter measurement during the de-integration phase.
