Short-Circuited to Ground
| Pin Name | Pin No. | Description of Potential Failure Effects | Failure Effect Class |
|---|---|---|---|
| IN+ | 1 | Device common-mode is tied to the negative rail. Depending on the circuit configuration, the output does not respond because the device is in an invalid, common-mode condition. | C |
| IN‒ | 3 | The device does not receive negative feedback. Depending on the circuit configuration, the output moves to the negative supply. | B |
| OUT | 4 | Depending on the circuit configuration, the device is forced into a short-circuit condition with the OUT voltage ultimately forced to the V‒ voltage. Prolonged exposure to short-circuit conditions can result in long-term reliability issues. | A |
| V+ | 5 | Op amp supplies are shorted together, leaving the V+ pin at some voltage between the V+ and V‒ sources (depending on the source impedance). | A |

Open-Circuited
| Pin Name | Pin No. | Description of Potential Failure Effects | Failure Effect Class |
|---|---|---|---|
| IN+ | 1 | Device common-mode is disconnected. The op amp is not provided with common-mode bias, and the device output results at the positive or negative rail. The IN+ pin voltage results at the positive or negative rail because of leakages on the ESD diodes. | B |
| V‒ | 2 | The negative supply remains floating. The op amp ceases to function because no current can source or sink to the device. | B |
| IN‒ | 3 | The inverting pin of the op amp is left floating. Negative feedback is not provided to the device, resulting in the device output moving between the positive and negative rails. The IN‒ pin voltage ends up at the positive or negative rail because of leakages on the ESD diodes. | B |
| OUT | 4 | There is no negative feedback or ability for OUT to drive the application. | B |
| V+ | 5 | The positive supply is left floating. The op amp ceases to function because no current sources or sinks to the device. | A |

Short-Circuited to Adjacent Pin
| Pin Name | Pin No. | Shorted to | Description of Potential Failure Effects | Failure Effect Class |
|---|---|---|---|---|
| IN+ | 1 | V‒ | Device common-mode is tied to the negative rail. Depending on the circuit configuration, the output does not respond because the device is in an invalid common-mode condition. | C |
| V‒ | 2 | IN‒ | The device does not receive negative feedback. Depending on the circuit configuration, the output moves to the negative supply. | B |
| IN‒ | 3 | OUT | Depending on the circuit configuration, the circuit gain is reduced to unity gain, and the application cannot function as intended. | B |
| OUT | 4 | V+ | Depending on the circuit configuration, the device is likely to be forced into a short-circuit condition with the OUT voltage ultimately forced to the V+ voltage. Prolonged exposure to short-circuit conditions can result in long-term reliability issues. | A |
| V+ | 5 | IN+ | Depending on the circuit configuration, the application likely does not function because device common-mode voltage is connected to V+. | B |

Supply
| Pin Name | Pin No. | Description of Potential Failure Effects | Failure Effect Class |
|---|---|---|---|
| IN+ | 1 | Depending on the circuit configuration, the application does not function because device common-mode voltage is connected to IN+. | B |
| V‒ | 2 | Op amp supplies are shorted together, leaving the V‒ pin at a voltage amount between the V‒ and V+ sources (depending on the source impedance). | A |
| IN‒ | 3 | The device does not receive negative feedback. Depending on the noninverting input voltage and circuit configuration, the output can move to the negative supply. | B |
| OUT | 4 | Depending on the circuit configuration, the device is forced into a short-circuit condition with the OUT voltage forced to the V+ voltage. Prolonged exposure to short-circuit conditions can result in long-term reliability issues. | A |
