I had a question regarding DACs. Can they accidentally spit out digital values? The output I am looking at seems to be fluctuating by discrete values and I was wondering if it was related to the DAC.
That's what DACs do -- they output an analog voltage (or current) that is related to the digital input.lcr2139 said:I had a question regarding DACs. Can they accidentally spit out digital values?

That looks to be a pretty good quality DAC, and has a guaranteed monotonic output:lcr2139 said:I am using the LTC2601. I would like to get rid of the noise that is coming out of it. How do I do this?
It's a precision 16 bit DAC. The problem is elsewhere, most likely. Why can't you use the UPLOAD feature to post a picture or scan of the schematic?lcr2139 said:I can't post a picture, but basically the temperature is jumping around between around 0.2 degrees C, peak to peak. It seems to go straight from one value to the next, instead of gradually changing. That is why I think it is a problem with the DAC.

A DAC, or digital-to-analog converter, is a device that converts digital signals into analog signals. This allows digital devices, such as computers, to interface with analog devices, such as speakers or motors.
A DAC outputs digital values by using a binary code to represent different voltage levels. The binary code is then converted into an analog signal, which can be measured as a voltage by the receiving device.
Yes, a DAC can accidentally spit out incorrect digital values if there are errors in the conversion process. This can happen due to noise, interference, or malfunctioning components. It is important to carefully design and test DAC systems to ensure accurate output.
In addition to external factors such as noise or interference, a DAC can also experience errors due to internal factors such as faulty components or incorrect programming. It is important to troubleshoot and identify the source of the error in order to fix it.
To ensure accurate output from a DAC, it is important to carefully design and test the system. This includes using high-quality components, minimizing noise and interference, and calibrating the DAC regularly. It is also important to monitor the system for any potential errors and troubleshoot them promptly.
