QUAD OP AMP
General DescriptionThe LM149 is a quad op amp. 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 single LM741 type op amp. Other features include input offset currents and
input bias current which are much less than those of standard LM741. Also, excellent
isolation between amplifiers has been achieved by independently biasing each amplifier and
using layout techniques which minimize thermal coupling. The LM149 has the same features
as the LM148 plus a gain bandwidth product of a 4 MHz at a gain of 5 or greater.
The LM149 can be used anywhere multiple LM741 or LM1558 type amplifiers are being used and
in applications where amplifier matching, high packing density, or high speed is required.
