AN68403 explains how to calibrate an analog signal chain by using a calibrated Delta Sigma ADC and an on-chip EEPROM that are available in PSoC® 3 and PSoC 5LP. An example of a programmable gain amplifier as part of the analog signal chain is also described. AN68403 shows how gain and offset errors can be eliminated in the entire signal chain.
