Data Acquisition System
1. An 9-bit A/D converter has a maximum output voltage of 511 volt. If
Vin = 400V, what is the output at the end of conversion on SAR?
2. Determine the (i) resolution; (ii) full-scale output and weight of each
input bit f car the DAC shown in the figure. Assume V REF =10V.
Determine also the full scale output when the feedback resistor Rf is
made one-fourth R.
3. Determine the output voltages caused by each bit in a 6-bit ladder if
the input levels are 0 = 0 V and l = + 16 V. Determine the resolution and
full-scale output of this circuit. Find out the voltage from the above
ladder for a digital input of “101011”.
