LM148/LM248/LM348  
Quad 741 Op Amps  
General Description  
The LM148 series is a true quad 741. 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  
741 operational amplifier. In addition the total supply current  
for all four amplifiers is comparable to the supply current of a  
single 741 type op amp. Other features include input offset  
currents and input bias current which are much less than  
those of a standard 741. Also, excellent isolation between  
amplifiers has been achieved by independently biasing each  
amplifier and using layout techniques which minimize ther-  
mal coupling.

The LM148 can be used anywhere multiple 741 or 1558 type  
amplifiers are being used and in applications where amplifier  
matching or high packing density is required. For lower  
power refer to LF444.
