A 6 bit DAC has a current output. For a digital input of 110010, the output current of 15mA is produced. What is the Output Current when the digital input is 111001?
Answer: B. 17.1mA — The current is proportional to the digital input value. 110010₂ = 50 gives 15 mA, and 111001₂ = 57, so output = 15 x 57 / 50 = 17.1 mA.
- A.
20mA
- B.
17.1mA
- C.
188.1mA
- D.
13.3mA

Show answer & explanation
Correct answer: B
The current is proportional to the digital input value. 110010₂ = 50 gives 15 mA, and 111001₂ = 57, so output = 15 x 57 / 50 = 17.1 mA.
