4 Pin Failure Mode Analysis (Pin FMA)

This section provides a Failure Mode Analysis (FMA) for the pins of the OPA2333-Q1 (SOIC and VSSOP package). The failure modes covered in this document include the typical pin-by-pin failure scenarios:

• Pin short-circuited to Ground (see Table 4-2 and Table 4-6.)
• Pin open-circuited (seeTable 4-3 and Table 4-7)
• Pin short-circuited to an adjacent pin (see Table 4-4 and Table 4-8)
• Pin short-circuited to supply (see Table 4-5 and Table 4-9)

Table 4-2 through Table 4-9 also indicate how these pin conditions can affect the device as per the failure effects classification in Table 4-1.

Following are the assumptions of use and the device configuration assumed for the pin FMA in this section:

• 'Short circuit to Power' means short to V+
• 'Short circuit to GND or Ground' means short to V‒
