Edinburgh College Digital to Analogue Converter Physics Question
Description
build a virtual Digital to Analogue Converter (DAC). Criteria is as follows:
- Construct a DAC to give 0.5 volt increments using a series of four switches and two op amps.
- Use 5V supply for the digital circuit and +/- 15V for op amp
- 0000= 0V
- 0001 = 0.5V
- 0010 = 1V
- 0011 = 1.5V
- 0100 = 2V
- 0101 = 2.5V
- 0110 = 3V
- 0111 = 3.5V
- 1000 = 4V
- 1001 = 4.5V
- 1010 = 5V
- 1011 = 5.5V
- 1100 = 6V
- 1101 = 6.5V
- 1110 = 7V
- 1111 = 7.5V
