A dual slope integrating type A/D converter has 5 μF capacitor and ...
The output voltage of dual slope integrating type AD converter,
= 80 t
Given that, output voltage cannot exceed 10 V
⇒ 80 t = 10 ⇒ 125 msec
= 80 t
Given that, output voltage cannot exceed 10 V
⇒ 80 t = 10 ⇒ 125 msec

A dual slope integrating type A/D converter has 5 main components:
1. Voltage reference: This component provides a stable and accurate reference voltage for the converter. It is usually generated using a precision voltage reference chip or by using a stable voltage source.
2. Switches: The switches are used to control the flow of current during the integration and measurement phases of the conversion process. These switches are typically MOSFETs or CMOS switches that can be controlled electronically.
3. Integrator: The integrator is responsible for integrating the input voltage during the integration phase. It consists of an operational amplifier and a capacitor. The capacitor charges or discharges depending on the input voltage, and the operational amplifier amplifies the voltage across the capacitor.
4. Counter: The counter is used to measure the time taken for the capacitor to charge or discharge during the integration phase. It counts the number of clock cycles required for the capacitor voltage to reach a certain threshold.
5. Digital logic: The digital logic circuitry is responsible for controlling the switches, counter, and other components of the A/D converter. It converts the analog voltage into a digital value based on the measured integration time.
Overall, the dual slope integrating type A/D converter works by integrating the input voltage for a fixed period of time and then integrating a known reference voltage for the same period of time. The digital output is then determined by comparing the integration times of the input voltage and the reference voltage.
