Q1:

A 2 bit BCD D/A converter is a weighted resistor type with ER = 1V, R = 1 MΩ and Rf = 10KΩ then Resolution in percent and volt is __________ .

A 1%, 1 mv

B 10%, 10 mv

C 10%, 1 mv

D 1%, 10 mv

ANS:D - 1%, 10 mv

Resolution % for BCD = where d is Resolution in volts. Resolution in volts = volts per step = 0.01V 0r 10mV.
