A temperature sensor has a sensitivity of $36$ micro$-$Volts$/,$ i$.$e$.$ for each degree difference in the junction temperature, the output changes by $36$ micro$-$Volts.$$

The sensor is to be used in a measurement system that must measure temperature with a resolution of $0\mathrm{.}7$ m$.$ The ADC in the measurement system would have output range of $5$ V$.$ What should be the minimum number of bits of the ADC that must be used in this measurement system?$$

Write your answer as a whole number $($e$.$g$.11)$; do not write any units or any symbol; just write the numerical value.$$

Please note:$$

$1$ m$=10-3$
