Understanding the 5-bit DAC
A 5-bit Digital-to-Analog Converter (DAC) can produce 2^5 = 32 different output levels. Each level corresponds to a specific digital input value ranging from 00000 (0) to 11111 (31). The output current scale is determined by the maximum output current and the digital input.
Given Information
- For a digital input of 10100 (which is 20 in decimal), the output current is 10mA.
- This means that the DAC’s output current increases linearly with the digital input value.
Calculating the Current per Step
To find the output current for any given digital input, we first determine the current per step:
- Maximum digital value: 31
- Output current for input 20: 10mA
Using this, we can calculate the current per increment:
- Current for each step = 10mA / 20 = 0.5mA per step
Finding the Output Current for 11101
Now, we need to calculate the output current for the input 11101, which is 29 in decimal.
- Steps from 0 to 29: 29 steps
- Therefore, the output current = 29 steps * 0.5mA/step = 14.5mA
Conclusion
The output current for the digital input of 11101 is:
- (a) 14.5mA
This calculation is possible due to the linear relationship between the digital input and the output current in the DAC. Thus, option (a) is the correct answer.
