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 stage—no 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

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.
