Note 2:
For supply voltages less than
±
15V the absolute maximum input voltage is equal to the supply voltage.
Note 3:
The maximum junction temperature of the LM119 is 150C, while that of the LM219 is 110C. For operating at elevated temperatures, devices in the H10
package must be derated based on a thermal resistance of 160C/W, junction to ambient, or 19C/W, junction to case. The thermal resistance of the J14 and N14
packages is 100C/W, junction to ambient.
Note 4:
These specifications apply for V
=
±
15V, and the Ground pin at ground, and 55C
≤
T
≤
+125C, unless otherwise stated. With the LM219, however, all
temperature specifications are limited to 25C
≤
T
≤
+85C. 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 5:
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 mA load. Thus, these
parameters define an error band and take into account the worst case effects of voltage gain and input impedance.
Note 6:
The response time specified (see definitions) is for a 100 mV input step with 5 mV overdrive.
Note 7:
Output is pulled up to 15V through a 1.4 k
resistor.
Note 8:
Refer to RETS119X for LM119H/883 and LM119J/883 specifications.
