Did we stress our LM6142 op-amp?
At ambient temperature, with about 20V applied between V+ and V-, the pin-1 output of an LM6142 amplifier, while at maximum output voltage, was connected through a 47-ohm resistor to a node that possibly was at -16VDC with respect to V-, for a time period of several minutes. The LM6142 TI datasheet specifies a maximum output current of ±25mA with a note that states that this "Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the maximum allowed junction temperature of 150°C". Can it be safely inferred that at ambient temperature this would cause no stress to the part, and that the maximum allowed junction temperature of 150°C would not be exceeded, especially since the TI datasheet also lists the “Output Short Circuit Current LM6142” in its “Sourcing” mode to be a maximum of 35mA?
We would greatly appreciate your determination on this question.
