someone pls save me before i go crazy...i need to design a 4-bit DAC similar to the 3-bit i uploaded but i need to know how the 3-bit performs before i can even attempt a 4bit.
can someone explain how fig 12.1 operates?
I am rebuilding the power supply in an arcade. I am replacing all of the components. If you look at the schematic, R5 is labeled as 25Ω, 5W. The actual resistor on the board was a 13Ω, 5W. The resistor is going to the input of a 7905 -5V regulator.
