LF444 Datasheet (National Semiconductor) - Quad Low Power JFET Input Operational Amplifier

LF444, Quad Low Power JFET Input Operational Amplifier

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 has the same bandwidth, slew rate, and gain (10 kΩ load) as the LM148 and only draws one fourth the su
