SFFS167B september 2021 – july 2023 ADS117L11 , ADS127L11 , ADS127L21
This section provides a failure mode analysis (FMA) for the pins of the ADS117L11 (WQFN package) ADS127L11 (TSSOP and WQFN packages), and ADS127L21 (WQFN package). The failure modes covered in this document include the typical pin-by-pin failure scenarios:
Table 4-6 through Table 4-9 also indicate how these pin conditions can affect the device as per the failure effects classification in Table 4-1.
Class | Failure Effects |
---|---|
A | Potential device damage that affects functionality. |
B | No device damage, but loss of functionality. |
C | No device damage, but performance degradation. |
D | No device damage, no impact to functionality or performance. |
Following are the assumptions of use and the device configuration assumed for the pin FMA in this section:
