The ADC 0808/0809
The ADC 0808/0809 is an 8-bit successive approximation analog-to-digital converter (ADC) that is commonly used in various applications. It converts analog voltage signals into corresponding digital values.

Successive Approximation ADC
The successive approximation ADC is a type of ADC that utilizes a binary search algorithm to convert analog signals into digital values. It works by comparing the input analog voltage with a reference voltage and making successive approximations to determine the digital output.

Conversion Delay
The conversion delay in an ADC refers to the time taken by the ADC to convert an analog input voltage into a digital value. It is the time required for the ADC to complete one conversion cycle.

ADC 0808/0809 Conversion Delay
According to the given question, the conversion delay in the ADC 0808/0809 is 100 microseconds. This means that it takes 100 microseconds for the ADC to complete one conversion cycle.

Importance of Conversion Delay
The conversion delay is an important parameter to consider when using an ADC in a system. It determines the maximum rate at which the ADC can sample and convert analog signals. If the conversion delay is too long, it can limit the overall speed and performance of the system.

Other Options
The other options provided in the question are:
a) 100 milliseconds
c) 50 milliseconds
d) none of these

According to the correct answer, none of these options are correct. The correct conversion delay for the ADC 0808/0809 is 100 microseconds.

Conclusion
In conclusion, the conversion delay in the successive approximation ADC 0808/0809 is 100 microseconds. This parameter is important to consider when designing systems that require fast and accurate analog-to-digital conversion.
