• Low input offset voltage: 1 mV
• Low input offset current: 2 nA
• Low input bias current: 30 nA
• Gain bandwidth product: 1.3 MHz
• High degree of isolation between amplifiers:
120 dB
• Overload protection for inputs and outputs
Description
The LM248 and LM348 consist 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 UA741
operational amplifier. In addition, the total supply
current for all four amplifiers is compatible with
the supply current of a single UA741 type
operational amplifier. Other features include input
offset current and input bias current which are
much less than those of a standard UA741. Also,
excellent isolation between amplifiers has been
achieved by independently biasing each amplifier
and using layout techniques which minimize
thermal coupling.
The LM248 and LM348 can be used where
multiple UA741 type amplifiers are being used
and in applications where amplifier matching or
high packaging density is required.
