Self-calibration7
- Learn about the self-calibration or internal calibration function in an analog-to-digital converter (ADC). (allaboutcircuits.com)
- In this article, we'll explore the self-calibration function. (allaboutcircuits.com)
- Self-calibration, sometimes called internal calibration, attempts to characterize and compensate for the offset and gain errors of the internal blocks of the ADC. (allaboutcircuits.com)
- For example, with a delta-sigma (ΔΣ) ADC that has an integrated PGA ( programmable gain amplifier ), a self-calibration removes the DC errors from both the PGA and the ΔΣ modulator. (allaboutcircuits.com)
- With some ADCs, such as the AD7124-4 , the self-calibration function can perform both offset (zero-scale) and gain (full-scale) calibrations. (allaboutcircuits.com)
