Answer:A
=9v×(0.5+0.25+0+0.125+7.8125×10-3+1.95 ×10-3) =9v×0.8547 =7.96v. 10. The basic step of a 8-bit DAC is 12.4mv.If the binary input 00000000 represents 0v. Determine the output, if the input is 101101111?
A. 1.36v B. 2.27v C. 5.45v D. None of the mentioned
Explanation: The output voltage for input 10110111 = 12.4mv ×[(1×27)+(0×26) + (1×25) + (1×24) + (0×23)+ (1×22) +(1×21)+ (1×20)] = 12.4× (128+32+16+4+2+1) =12.4mv×183=2.27v. Sanfoundry Global Education & Learning Series – Linear Integrated Circuit.
