Q. Which of the following key specifications are essential for the selection of digital to analog converter from application point of view?- Published on 23 Oct 15a. Response time
b. Conversion time
c. Resolution & Settling time
d. None of the above
ANSWER: Resolution & Settling time
By taking into consideration the approach of application point of view, selection of an efficient digital to analog converters must have good specifications in terms of resolution, linearity or non-linearity of error, Gain & offset errors along with the settling time. Resolution specifies the number of input bits with the valuation in the form of least significant bit (LSB) whereas the settling time implies the requirement of time for DAC output to settle down between positive or negative ½ LSB of the final value of digital input (which is generally zero to full scale). However, response & conversion time are not the valid specifications for DAC selection since they are of significant importance in ADC.
