Explanation: The polarity of the reference voltage is accordance with the type of the switch used. For example, in TTL switches, the reference voltage should be +5v and the output will be negative. 7. What is the disadvantage of binary weighted type DAC?
A. Require wide range of resistors
B. High operating frequency
C. High power consumption
D. Slow switching
