LM248, LM348 Four UA741 quad bipolar operational amplifiers Datasheet - production data Description The LM248 and LM348 consist of four independent, high-gain internally-compensated, D SO14 low-power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar UA741 operational amplifier. In addition, the total supply current for all four amplifiers is compatible with the supply current of a single UA741 type operational amplifier. Other features include input offset current and input bias current which are much less than those of a standard UA741. Also, excellent isolation between amplifiers has been achieved by independently biasing each amplifier and using layout techniques which minimize thermal coupling. Pin connections (top view) The LM248 and LM348 can be used where multiple UA741 type amplifiers are being used and in applications where amplifier matching or Features high packaging density is required. • Low supply current: 0.53 mA per amplifier Table 1.

For supply voltages less than the maximum value, the absolute maximum input voltage is equal to the supply voltage. 2. Any of the amplifier outputs can be shorted to ground indefinitely, however, more than one should not be simultaneously shorted as the maximum junction will be exceeded. 3. Human body model: 100pF discharged through a 1.5kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating. 4. Machine model: a 200pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5Ω), done for all couples of pin combinations with other pins floating. 5. Charged device model: all pins plus package are charged together to the specified voltage and then discharged directly to the ground. 4/10 DocID2161 Rev 5
