I need please ideas how to use DAC to measure current.Currently I have built DAC to measure voltage, the type i built is the STAIRSTEP RAMP the 8 bit one.
is to connect a small resistor in series and measure the voltage across the resistor
An ADC, or analog-to-digital converter, is a device that converts analog signals, such as voltage or current, into digital signals that can be read and processed by a digital system.
An ADC measures current by converting the analog current signal into a digital value. This is done by sampling the current signal at regular intervals and assigning a digital value based on the amplitude of the signal at each sample.
The resolution of an ADC refers to the number of discrete values that the ADC can assign to the input signal. It is typically measured in bits, with higher bit resolutions resulting in more precise digital values.
When choosing an ADC for measuring current, it is important to consider factors such as the input range and resolution needed, as well as the sampling rate and accuracy of the ADC. Additionally, the type of current being measured (AC or DC) and the desired level of noise reduction should also be taken into account.
While ADCs are commonly used for measuring current, there are some limitations to consider. These include the accuracy and linearity of the ADC, as well as the potential for errors due to noise and aliasing. It is important to carefully select and calibrate the ADC to minimize these limitations.
