Description
The LM148 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 currents 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 type
amplifiers are being used and in applications where amplifier
matching or high packing density is required.
