Analog Signal Chain Calibration

Analog signal chains are prone to gain and offset errors that can propagate through the signal chain and reduce accuracy. Even a simple signal chain, such as one consisting of a sensor whose weak analog signal is first amplified and then fed to ADC before being converted to a digital value, can be negatively impacted by these types of errors.  This white paper will show how to use calibration to eliminate these errors from the entire signal chain using a calibrated delta sigma ADC and an on-chip EEPROM.
