Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test  conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.

Note 2: The differential input voltage range shall not exceed the supply voltage range. 

Note 3: Any of the amplifier outputs can be shorted to ground indefinitely; however, more than one should not be simultaneously shrted as the maximum junction temperature will be exceeded.

Note 4: The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by TjMAX, ThetaJA, and the ambient temperature, TA. The maximum available power dissipation at any temperature is Pd=(TjMAX - TA)/ThetaJA or the 25 C PdMAX, whichever is less.

Note 5: Human body model, 1.5K Ohms in series with 100pF.


Description

The LM148 series is a true quad LM741. It consists of four independent, high gain,internally compensated, low power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar LM741 operational amplifier. In addition the total supply current for all four amplifiers is comparable to the supply current of a LM741 type op amp. Other features of LM148 series include input offset currents and input bias current which are much less than those of a standard LM741. Also, excellent isolation between amplifiers LM148 series has been achieved by independently biasing each amplifier and using layout techniques which minimize thermal coupling.

The LM148 can be used anywhere multiple LM741 or LM1558 type amplifiers are being used and in applications where amplifier matching or high packing density is required.
