LM3489MMX - Brand New Texas Instruments DC DC Switching Controllers
-
Description
The LM3489MMX is a DC DC switching controller model in the electronic component category. It is a true quad LM741, consisting of four independent, high-gain, internally compensated, low-power operational amplifiers. The LM3489MMX is designed to provide functional characteristics identical to those of the familiar LM741 operational amplifier. It has a total supply current comparable to that of a single LM741 type OP Amp. Moreover, it features input offset currents and input bias current which are much less than those of a standard LM741. The LM3489MMX also achieves excellent isolation between amplifiers by independently biasing each amplifier and using layout techniques that minimize thermal coupling.
