Part Number	LF444 Datasheet
Manufacturer	National Semiconductor
Overview	The LF444 quad low power operational amplifier provides many of the same AC characteristics as the industry standard LM148 while greatly improving the DC characteristics of the LM148. The amplifier ha. n n n n n 1⁄4 supply current of a LM148: 200 µA/Amplifier (max) Low input bias current: 50 pA (max) High gain bandwidth: 1 MHz High slew rate: 1 V/µs Low noise voltage for low power n Low input noise current n High input impedance: 1012Ω n High gain VO = ± 10V, RL = 10k: 50k (min) Simplified Sch.
