description/ordering information
The LM148, LM248, and LM348 are quadruple,
independent, high-gain, internally compensated
operational amplifiers designed to have operating
characteristics similar to the
A741. These
amplifiers exhibit low supply-current drain and
input bias and offset currents that are much less
than those of the
A741.

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:
1. All voltage values, unless otherwise noted, are with respect to the midpoint between VCC+ and VCC.
2. Differential voltages are at IN+ with respect to IN.
3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or the value specified in the table,
whichever is less.
4. The output may be shorted to ground or either power supply. Temperature and/or supply voltages must be limited to ensure that
the dissipation rating is not exceeded.
5. Maximum power dissipation is a function of TJ(max),
JA, and TA. The maximum allowable power dissipation at any allowable
ambient temperautre is PD = (TJ(max) TA)/
JA. Operating at the absolute maximum TJ of 150
C can affect reliability.
6. The package thermal impedance is calculated in accordance with JESD 51-7.
7. Maximum power dissipation is a function of TJ(max),
JC, and TC. The maximum allowable power dissipation at any allowable
ambient temperautre is PD = (TJ(max) TC)/
JC. Operating at the absolute maximum TJ of 150
C can affect reliability.
8. The package thermal impedance is calculated in accordance with MIL-STD-883.
