What is the real resolution of my voltage measurement when I use only some of the range of of the ADCchannel
I have a 16 bit ADC, I use the +/1 V range, differential channel. If I used the full range of the ADC to provide full resolution (I am aware non-linearity and noise may affect this) this calculates as:...

Code transition glitches in an ideal DAC
I have read in most books and articles that a code-to-code glitch is caused by imperfect timing in the switching of bits into a DAC.
If that was true, then there should be no glitch when you use an ...

Are there monochrome camera sensors with more than 16 bit depth per pixel?
Some camera use cases (like exoplanet transit photometry) require measuring smaller variations in brightness across an image and over time than the bit depth resolution in 16 bit monochrome cameras ...

ADC Oversampling New Resolution
I am using an ADC LTC2378 with a resolution of 20 bits.
Based on the datasheet this resolution corresponds to an LSB calculated by the equation (\$2 V_{\text{ref}}/2^{20}\$), i.e., 9.536 µV.
In order ...

PWM DAC, dividing the 8 bit PWM DAC in 2 four bit PWM DAC [closed]
Can anybody explain what the purpose is of dividing an 8 bit DAC using PWM in two 4 bits DAC and how is it made possible the scaling of PWMH and PWML and how do they affect in total uncertainty.
https:...

Melexis MLX90395 sensor resolution
I have a Melexis MLX90395 Hall magnetic field sensor, whose datasheet says that the sensitivity is 2.5 uT/LSB.
My question is, does this mean that the resolution, i.e. the minimum value of the ...

DC offset to an ADC reduces dynamic range which reduces accuracy. How to quantify accuracy due to loss of dynamic range?
It’s understood that the dynamic range of the ADC should match the max amplitude of the signal to achieve maximum accuracy. If it doesn’t, you lose digital codes which reduces accuracy.
How can one ...

Is it okay to split the same net to sample an analog signal in two ADCs?
I have an analog signal that comes from another place with a range of 0-1 V, the required resolution should be 10 bit.
I want to sample the same signal in two ADCs, the internal ADC of the STM32, and ...

Sensors data-sheet is unclear about resolution of readings
This sensor states that its lower detectable limit is 1ppm yet its resolution is 0.1ppm.
What is the difference between resolution and lower-detectable limit?
I thought resolution was the smallest ...

ADC resolution impact with voltage divider
I have a sensor that outputs a signal change between -4 to 4 V.
I want to use a bipolar ADC with a 3.3 V reference. I know that I should use a voltage divider, but what is the impact on resolution? I ...

STM32H745XI graphical display
I am planning to interface an STM32H745XI to a 1400x480 display. The maximum resolution given for the STM is 480×480. I understand that this is the maximum frequency the device can actually output.

How to measure bit resolution
I have a system that has a bit resolution of 1.9uV (gain 20), to increase the bit resolution the gain stage was increased at the input of 180V/V which lowers the effective bit resolution to 0.21uV.
I ...

Mapping different resolution ADC to DAC
I have a 24-bit ADC that is controlled by an FPGA. I want to take the ADC input and output it from a 16-bit DAC that is also controlled by the FPGA.
Do I simply ignore the 8 LSB bits of the data and ...

Time domain reflectometry and resolution
Regarding the temporal (and consequently spatial) resolution of a TDR system, I've read from different sources that the maximum resolution achievable is half of the rising time of the input step ...
