How to use ADC to measure chained battery?
I have developed an ADC board using AD7192 to measure battery voltage. Assume each battery is 3V, the chained battery in series would gives 15V in total. Let the battery be BAT1+, BAT1-, BAT2+, BAT2- ....

ADC DNL INL Confusion
The DNL of an ADC is defined as the measured code width versus the ideal LSB code width.
The INL is the integral of the DNL (or the running sum of it).
But the INL has two methods - end point and best ...

Not correct reading in ADCs DACs integrated system
I made a ADCs board (AD7194) and DACs board (AD5689). Each DAC (separated ground) could output 0-5V, and Each ADC channel could measure 0-3.3V. I used a voltage divider network to turn 0-5V to 0-3.3V. ...

Simplest JFET front end to A/D converter
This is regarding a cheap Pmod I2S2 ADC and DAC (connected to an STM32F407G-DISC1) that uses a Cirrus CS5343 ADC.
Now, as best as I can tell from the CS5343 data sheet, the \$ V_{PP} \$ of the input ...

How do I create a circuit to reliably calculate a range of unknown resistances?
I'm designing a low power circuit which serves to determine the unknown resistance across a 16 channel sensor. So far the results are bit subpar. The resistances are a function of a different applied ...

Is this extra cycle before the MSB a common thing with serial bit timing?
The products that this is specifically around are the Pmod I2S2 which uses the Cirrus CS5343 ADC and CS4344 DAC. It is plugged into a STM32F407G-DISC1.
Now I am having some trouble figuring out ...

How to understand and compare ADC errors between LTC2314-14 and internal ADC of STM32F103
We are going to sample and curve a short, fast-changing signal of around 34 us, with a reasonable resolution of at least 10 bits.
A 4 Msps ADC would provide us around ~138 data points in 34 us
The ...
