FK PACKAGE (TOP VIEW) 1IN – 1OUT NC 4OUT 4IN – 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. 1IN + NC VCC + NC 2IN + 3 2 1 20 19 18 5 17 6 16 7 15 8 14 9 10 11 12 13 4IN + NC VCC – NC 3IN + 2IN – 2OUT NC 3OUT 3IN – 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. 4 symbol (each amplifier) NC – No internal connection + IN + OUT – IN – AVAILABLE OPTIONS PACKAGE TA VIOmax AT 25°C SMALL OUTLINE (D) CHIP CARRIER (FK) CERAMIC DIP (J) PLASTIC DIP (N) TSSOP (PW) 0°C to 70°C 6 mV LM348D — — LM348N LM348PW – 25°C to 85°C 6 mV LM248D — — LM248N — – 55°C to 125°C 5 mV — LM148FK LM148J — — The D package is available taped and reeled.

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.
