LF444CN/NOPB

The LF444CN/NOPB is a 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 has the same bandwidth, slew rate and gain (10kΩ load) as the LM148 and only draws one fourth the supply current of the LM148. In addition the well matched high voltage JFET input devices of the LF444CN/NOPB reduce the input bias and offset currents by a factor of 10,000 over the LM148. Also has a very low equivalent input noise voltage for low power amplifier. The LF444CN/NOPB pin is compatible with the LM148 allowing an immediate 4 times reduction in power drain in many applications. It should be used wherever low power dissipation and good electrical characteristics are the major considerations.

• Low input bias current (50pA max)
• High gain bandwidth (1MHz)
• High slew rate
• Low noise voltage for low power 35nV/√Hz
• Low input noise current (0.01pA/√Hz)
• High input impedance (10¹²Ω)
• High gain (50k min)
• Green product and no Sb/Br
