LF441 Datasheet Low Power JFET Input Operational Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LF441 Low Power JFET Input Operational Amplifier Obsolete February 1995 LF441 Low Power JFET Input Operational Amplifier.

General Description

The LF441 low power operational amplifier provides many of the same AC characteristics as the industry standard LM741 while greatly improving the DC characteristics of the LM741 The amplifier has the same bandwidth slew rate and gain (10 kX load) as the LM741 and only draws one tenth the supply current of the LM741 In addition the well matched high voltage JFET input devices of the LF441 reduce the input bias and offset currents by a factor of 10 000 over the LM741 A bination of careful layout design and internal trimming guarantees very low input offset voltage and voltage drift The LF441 also has a very low equivalent input noise voltage for a low power amplifier The LF441 is pin patible with the LM741 allowing an immediate 10 times reduction in power drain in many applications The LF441 should be used where low power dissipation and good electrical characteristics are the major considerations
