The gain and offset errors of the ADC can be measured and compensated using some calibration procedures. When offset and gain errors are compensated for, the actual transfer function should now be equal to the transfer function of perfect ADC. However, non-linearity in the ADC may cause the a...
The “ESP32 ArduinoCore Interface – ADC” provides a seamless integration between the ESP32 microcontroller and the Arduino development environment, specifically focusing on the Analog-to-Digital Converter (ADC) functionality. ADC TermDescription ADC Analog-to-Digital Converter – A device or circuit ...
The AD7643 is designed to interface with a parallel 8-bit or 16-bit wide interface or with a general-purpose serial port or I/O ports on a microcontroller. A variety of external buffers can be used with the AD7643 to prevent digital noise from coupling into the ADC. The SPI Interface ...
An ideal ADC can be described mathematically by a linear transfer function, as shown in Figure 1-5 and Figure 1-6. 1.6 Perfect ADC To define a perfect ADC, the concept of quantization must be used. Due to the digital nature of an ADC, continuous output values are not possible. The per...

I've implemented a bit-banged SPI readout function. It turns on the ADC power, after a while it activates CS_N and then clocks the data out as fast as possible. The first sample is ignored, the 2nd sample is used. The data of this 2nd sample...
Start-up time of a voltage reference circuit is a function of output load capacitance and voltage level. Most microcontroller applications may not require continuous operation. There are applications where the ADC circuit will be turned off and will be switched on when required. The on-time of ...
