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 µA741. These

amplifiers exhibit low supply-current drain and

input bias and offset currents that are much less

than those of the µA741.

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 V

and V .

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 T (max), θ , and T . The maximum allowable power dissipation at any allowable

ambient temperautre is P = (T (max) – T )/θ . Operating at the absolute maximum T 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 T (max), θ , and T . The maximum allowable power dissipation at any allowable

ambient temperautre is P = (T (max) – T )/θ . Operating at the absolute maximum T of 150°C can affect reliability.

8. The package thermal impedance is calculated in accordance with MIL-STD-883.
