KA248/KA348
Quad Operational Amplifier
Description
The KA248/KA348 is a true quad KA741. 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
KA741 operational amplifier. In addition the total supply
current for all four amplifiers is comparable to the supply
current of a single KA741 type OP Amp. Other features
include input offset currents and input bias current which are
much less than those of a standard KA741. Also, excellent
isolation between amplifiers has been achieved by
independently biasing each amplifier and using layout
techniques which minimize thermal coupling.
