Dual slope ADC is the best example of an Indirect type ADC.
. A double slope integrating ADCAnalog To Digital Converter is provided to minimize a chip area by forming a switch control logic circuit part with a MCUMicro Control Unit and a. For clarity the details of the INS8070 microprocessor and its associated logic are shown in. Dual slope aid converters adc-14 i adc-17 i adciioo.
An Analog to Digital Converter ADC converts an analog signal into a digital signal. The digital signal is represented with a binary code which is a combination of bits 0 and 1. The analog signal is first applied to the sample block where it is sampled at a specific sampling frequencyThe sample amplitude value is maintained and held in the hold block.

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.
The integrator uses a resistor at the input which along with. Block diagram adclloo 48 47 n1. Dual-slope integration has many.
As the name suggests a dual slope ADC produces an equivalent. The sensor S1 produces 20mVV at full scale Figure 2. Diagram is shown in Figure 1 and the integrator output waveforms are shown in Figure 2.
For a 36V Li cell therefore the output is 20mVV 36V 72mV. Figure 2 Dual-slope ADC block diagram A two-stage op-amp is used in the analog sub-unit as an Integrator and a Comparator. Equal to t 1 the input voltage is disconnected and the integrator input is connected to a negative voltage e r The integrator output will have a negative slope which is constant and.
Dual Slope ADC Integrator Output Waveforms. The first integration slope differs depending on the value of the input voltage while the second slope is constant and depends on VREF which is itself constant.
