SFFS559 March 2023 ADS1014-Q1
The failure mode distribution estimation for the ADS1014-Q1 in Table 3-1 comes from the combination of common failure modes listed in standards such as IEC 61508 and ISO 26262, the ratio of sub-circuit function size and complexity and from best engineering judgment.
The failure modes listed in this section reflect random failure events and do not include failures due to misuse or overstress.
| Die Failure Modes | Failure Mode Distribution (%) |
|---|---|
| Channel-channel short | 10% |
| ADC output code bit error | 20% |
| ADC gain out of specification | 20% |
| ADC offset out of specification | 20% |
| Communication error | 25% |
| ALERT/RDY pin false trip or fails to trip | 5% |
