FEATURES

DESCRIPTION

The LM148 series is a true quad 741. It consists of

2

•

741 Op Amp Operating Characteristics

four independent, high gain, internally compensated,

•

Class AB Output Stage—No Crossover

low power operational amplifiers which have been

Distortion

designed

to

provide

functional

characteristics

•

Pin Compatible With the LM124

identical to those of the familiar 741 operational

amplifier. In addition the total supply current for all

•

Overload Protection for Inputs and Outputs

four amplifiers is comparable to the supply current of

•

Low Supply Current Drain: 0.6 mA/Amplifier

a single 741 type op amp. Other features include

•

Low Input Offset Voltage: 1 mV

input offset currents and input bias current which are

much less than those of a standard 741. Also,

•

Low Input Offset Current: 4 nA

excellent isolation between amplifiers has been

•

Low Input Bias Current 30 nA

achieved by independently biasing each amplifier and

•

High Degree of Isolation Between Amplifiers:

using layout techniques which minimize thermal

120 dB

coupling.

•

Gain Bandwidth Product

The LM148 can be used anywhere multiple 741 or

amplifiers

are

being

used

and

in

applications where amplifier matching or high packing

density is required. For lower power refer to LF444.
