Note 9:
For supply voltages less than
±
15 the absolute maximum input voltage is equal to the supply voltage.
Note 10:
The maximum junction temperature of the LM319A and LM319 is 85C. For operating at elevated temperatures, devices in the H10 package must be de-
rated based on a thermal resistance of 160C/W, junction to ambient, or 19C/W, junction to case. The thermal resistance of the N14 and J14 package is 100C/W,
junction to ambient. The thermal resistance of the M14 package is 115C/W, junction to ambient.
Note 11:
These specifications apply for V
=
±
15V, and 0C
≤
T
≤
70C, 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 V
S
.
Note 12:
The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1 mAload. Thus, these
parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
Note 13:
The response time specified is for a 100 mV input step with 5 mV overdrive.
Note 14:
Output is pulled up to 15V through a 1.4 k
resistor.
