LM148QML  
Quad 741 Op Amps  
General Description  
Features  
n 741 op amp operating characteristics  
The LM148 is a true quad LM741. It consists of four inde-  
pendent, high gain, internally compensated, low power op-  
erational 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 single LM741 type op amp. Other features  
include input offset currents and input bias current which are  
much less than those of a standard LM741. Also, excellent  
isolation between amplifiers has been achieved by indepen-  
dently biasing each amplifier and using layout techniques  
which minimize thermal coupling.  
n Class AB output stageno crossover distortion  
n Pin compatible with the LM124  
n Overload protection for inputs and outputs  
n Low supply current drain:  
n Low input offset voltage:  
n Low input offset current:  
n Low input bias current  
n High degree of isolation between amplifiers:  
n Gain bandwidth product (unity gain):  
0.6 mA/Amplifier  
1 mV  
4 nA  
30 nA

1.0 MHz  
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.
