Note 10: For supply voltages less than ±15 the absolute maximum input voltage is equal to the supply voltage.
Note 11: The maximum junction temperature of the LM319A and LM319 is 85˚C. For operating at elevated temperatures, devices in the H10 package must be de-
rated based on a thermal resistance of 160˚C/W, junction to ambient, or 19˚C/W, junction to case. The thermal resistance of the N14 and J14 package is 100˚C/W,
junction to ambient. The thermal resistance of the M14 package is 115˚C/W, junction to ambient.
Note 12: These specifications apply for VS = ±15V, and 0˚C ≤ TA ≤ 70˚C, unless otherwise stated. The offset voltage, offset current and bias current specifications
apply for any supply voltage from a single 5V supply up to ±15V supplies. Do not operate the device with more than 16V from ground to VS.
Note 13: The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply witha1mA load. Thus, these
parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
Note 14: The response time specified is for a 100 mV input step with 5 mV overdrive.
Note 15: Output is pulled up to 15V through a 1.4 k
Ω resistor.
