Unstable Power Supply

Exceeding the maximum voltage or current limits specified by the ADC data sheet can lead to non-ideal behavior, significant performance degradation, or even device failure. Operating the ADC beyond the recommended range can result in the gain and or offset errors significantly degrading SFDR. In such an event, upon the return of normal power conditions, a re-calibration can make sure that accurate measurements return, however, reprogramming of the device can be required to guarantee system performance.
