Table 4-2 Pin FMA for Device Pins Short-Circuited to Ground
Pin NamePin No.Description of Potential Failure EffectsFailure Effect Class
OUT1Short to GND may cause device to overheat.B
VS-2Normal operation if single supply configuration is used.D
IN+3Input at VS- (GND) is valid input, however, desired application result is unlikely.C
IN-4Input at VS- (GND) is valid input, however, desired application result is unlikely.C
VS+5Diodes from input to VS+ may turn on due to input signal and cause electrical overstress (EOS).A
Table 4-3 Pin FMA for Device Pins Open-Circuited
Pin NamePin No.Description of Potential Failure EffectsFailure Effect Class
OUT1Output can be left open. There is no effect on the device, but the output will not be measured.C
VS-2Lowest voltage output pin will try to power the VS-pin of the device.B
IN+3Floating input, circuit will likely not function as expected.C
IN-4Floating input, circuit will likely not function as expected.C
VS+5Highest voltage output pin will try to power the VS+ pin of the device.B

Pin NamePin No.Shorted toDescription of Potential Failure EffectsFailure Effect Class
OUT1VS-Short to VS- may cause device to overheat.B
VS-2IN+Input at V- (GND) is valid input, however, desired application result is unlikely.C
IN+3IN-No damage to device. Application circuit will not work. Pins are not adjacent to each other.C
IN-4VS+May cause device to overheat. Input at VS+ is not a valid input. Pins are not as near to each other, due to package type.B
VS+5OUTShort to VS+ may cause device to overheat. Pins are not adjacent to each other.B
