FEATURES

DESCRIPTION

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

•

741 Op Amp Operating Characteristics

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 thermal

coupling.

Class AB Output Stage—No Crossover

Distortion

•

Pin Compatible With the LM124

Overload Protection for Inputs and Outputs

Low Supply Current Drain: 0.6 mA/Amplifier

Low Input Offset Voltage: 1 mV

Low Input Offset Current: 4 nA

Low Input Bias Current 30 nA

High Degree of Isolation Between Amplifiers:

120 dB

•

Gain Bandwidth Product

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.
