$13\mathrm{.}1$:$$ PARALLEL AND SERIAL ADC

$1.$ Give the values of CS and WR in order to start conversion for the ADC$0804.$

$2.$ Give the values of CS and RD in order to get data from the ADC$0804.$

$3.$ In the ADC$0804,$ what happens to the converted analog data? How do we know if the ADC is ready to provide us the data?

$4.$ In the ADC$0804,$ what happens to the old data if we start conversion again before we pick up the last data?

$5.$ From the viewpoint of the ADC$0804,$ INTR is an $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_($input$,$ output$)$ signal. What is its function in the ADC$0804?$

$6.$ For an ADC$0804$ chip, find the step size for each of the following V ref $/2$ values.

$($a$)$ V ref $/2=1\mathrm{.}28$ V$($b$)$ V ref $/2=1$ V $($c$)$ V ref $/2=1\mathrm{.}9$ V

$7.$ In the ADC$0804,$ what is the role of pins V in $(+)$and V in $(-)?$

$8.$ With a step size of $19\mathrm{.}53$ mV$,$ what is the analog input voltage if all outputs are $1?$

$9.$ True or false. ADC$0804$ is an $8-$bit ADC.

$10.$ Which of the following ADC sizes provide the best resolution?

$($a$)8-$bit$($b$)10-$bit$($c$)12-$bit$($d$)16-$bit$($e$)$ They are all the same.

$11.$ Calculate the step size for the following ADCs, if V ref $$is $5$ V$.$

$($a$)8-$bit$($b$)10-$bit$($c$)12-$bit$($d$)16-$bit
