Observed a 0.4v difference between the actual analog voltage and the voltage read with Internal Analog Reference 1.1v, when an external analog reference voltage is connected to the AREF pin of Arduino ...
The AD4116 is a low power, low noise, 24-bit, Σ-Δ analog-to-digital converter (ADC) that integrates an analog front end (AFE) for six fully differential or eleven single-ended, high impedance (≥10 MΩ) ...
Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal or ...
