LM348/LM248

Quad Operational Amplifier

Features

Description

• LM741 OP Amp operating characteristics

• Low supply current drain

• Class AB output stage no crossover distortion

• Pin compatible with the LM324/LM248

• Low input offset voltage : 1mV Typ.

• Low input offset current : 4nA Typ.

TheLM348/LM248 is a true quad LM741. 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 a standard LM741. Also, excellent

isolation between amplifiers has been achieved by

• Low input bias current : 30nA Typ.

• Gain bandwidth (unity gain): 1.0MHz Typ.

• High degree of isolation between amplifiers: 120dB

• Overload protection for inputs and outputs

independently biasing each amplifier and using layout

techniques which minimize thermal coupling.
