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.
