Description

The LM3485LED EVAL is a quad operational amplifier model, similar to the LM741. It consists of four independent, high-gain, internally compensated, low power operational amplifiers. These amplifiers are designed to have the same functional characteristics as the LM741 without the drawbacks. The total supply current for all four amplifiers is comparable to that of a single LM741, and the input offset currents and input bias current are much lower. Additionally, the amplifier's isolation between each other is excellent, achieved by biasing each amplifier independently and using effective layout techniques to minimize thermal coupling.
