AN84783 shows how to increase the accuracy of measurements using the 20-bit Delta-Sigma ADC in PSoC 3 and PSoC 5LP. Major topics include effective resolution, gain and offset errors, non-linearity, and accuracy improvement techniques. A spreadsheet is provided to assist ADC performance analysis and to optimize ADC Component configuration.

はじめに

Accurate measurement of physical quantities is important for many applications. In most measurement systems, you use a transducer to convert a physical quantity to a voltage. This voltage is sent through signal conditioning circuitry, if necessary, and then to an analog-to-digital converter (ADC).
