description

LM148 . . . FK PACKAGE

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.

The LM148 is characterized for operation over the full military temperature range of ±55°C to 125°C, the LM248 is characterized for operation from ±25°C to 85°C, and the LM348 is characterized for operation from 0°C to 70°C.

NOTES: 1. All voltage values, except differential voltages, 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.
