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