Hi, thanks for the reply, the diagraim was presented that way for me to do the calculations, i have also seen related diagraim online for DAC!berkeman said:That doesn't look right to me. You also can't get 10V out if the power supplies are +/-9V.
Are you trying to make an R2R ladder DAC?
berkeman said:Well, can you explain this first line from your diagram? It doesn't make sense past the 900mV number...
Vout = (9V x 470/4700) = 900mV = 800mV = 8V
And why are the resistor values in your table different from the schematic?
A DAC-op-amp, or digital-to-analog converter operational amplifier, is a device used to convert digital signals into analog signals.
A DAC-op-amp is typically used in circuit design as a component for converting digital signals from a microcontroller or other digital device into analog signals for controlling analog devices, such as motors or sensors.
The most important factors to consider when calculating a DAC-op-amp circuit are the desired output voltage range, the input voltage range, the resolution of the digital signal, and the required accuracy and precision of the analog output.
To ensure the accuracy of your DAC-op-amp calculation, it is important to double check your calculations and verify that all necessary components are included in the circuit. You can also use simulation software or test the circuit in a controlled environment to confirm the expected output.
Some common mistakes to avoid when working with DAC-op-amps include using incorrect input voltage ranges, not taking into account the power supply limitations, and not considering the effects of noise and interference on the circuit. It is also important to carefully select the appropriate op-amp for your specific application.
