General Description
The LM148 series is a true quad 741. 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
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.
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.
