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.
