LF412CN Description

LF412CN are JFET input operational amplifiers with very low input offset voltage and input offset voltage drift that are cheap cost and high speed. Low supply current is required for the LF412CN amplifier to maintain a broad gain bandwidth product and a quick slew rate. Furthermore, well-matched high voltage JFET input devices have extremely low input bias and offset currents. Because the LF412-N dual is pin compatible with the LM1558, designers can quickly improve the overall performance of their existing systems.
