It did not give any other details. If you could please explain the theory behind this.If 1 count is 15.625mV how many counts in 9.140625V?
if that so, why they given the reference voltage ?If one potato weighs 100g how many potatoes in a 1kg bag of potatoes?
Notice that they don't tell you how many bits the DAC is. Another question probably asks you to find that.if that so, why they given the reference voltage ?
They asked the following two questions and I don't clearly understand what it means.Notice that they don't tell you how many bits the DAC is. Another question probably asks you to find that.
1) Draw a block diagram to interface an 8 bit ADC with 8051. Clearly show your calculations
and assumptions to use above DAC to set the ADC reference voltage 10 V and display the
result in three seven segment displays.
2)
Draw a flowchart to measure analog voltage 5 V using above ADC and DAC. Display the
result in three seven segment displays. Clearly show your calculations and assumptions.
What don't you understand?They asked the following two questions and I don't clearly understand what it means.
The n-bit R/2R digital-to-analog converter (DAC) has a reference of 16 V and the analog
output for the input code 1 is 15.625 mV. how to find the digital input value for the output
9.140625 V ??
I don't understand the following things related to the question.What don't you understand?
Still waiting to see some attempt on your part.
Do you have any theory notes related to this ?for code 1 : 15.625 mV
1 V : 1000/15.625
9.140625V = (1000*9.140625)/15.625 = 585
in binary : 1001001001
