$1-$Temperature sensor values from $\backslash (-40^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ to $\backslash (80^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ are input data for a microprocessor controller. It is desired that the temperature is decided within $\backslash (0\mathrm{.}5^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$

Are $8$ bits DAC sufficient? If so$,$ what is the resolution?

$2-$An $12-$bit ADC has a reference voltage of $12$ V and an analog input of $3\mathrm{.}7$ V $.$ Find the binary output.
