@ -6,7 +6,7 @@ Analog to Digital Converter (ADC) Calibration Driver
Introduction
------------
In {IDF_TARGET_NAME}, the digital-to-analog converter (ADC) compares the input analog voltage to the reference, and determines each bit of the output digital result. By design, the ADC reference voltage for {IDF_TARGET_NAME} is 1100 mV. However, the true reference voltage can range from 1000 mV to 1200 mV among different chips. This guide introduces the ADC calibration driver to minimize the effect of different reference voltages, and get more accurate output results.
