KA248/KA348

QUAD OPERATIONAL AMPLIFIER

QUAD OPERATIONAL AMPLIFIERS

The KA248/KA348 is a true quad KA741. It consists of four independ-

14 DIP

ent, 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.
