LF442 dual low power operational amplifiers, LM1458' It provides many of the same AC characteristics as the industry standard LM1458 while greatly improving its DC capabilities. The amplifiers have the same bandwidth, slew rate, and gain as the LM1458 (10 kΩ load) and draw only one-tenth of the LM1458's supply current. Additionally, the LF442's well-matched high-voltage JFET input devices reduce input bias and offset currents by a factor of 10,000 over the LM1458. The combination of careful layout design and internal clipping ensures very low input offset voltage and voltage drift. The LF442 also has a very low equivalent input noise voltage for a low-power amplifier.
