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 k
tenth the supply current of the LM741 In addition the well
matched high voltage JFET input devices of the LF441 re-
duce the input bias and offset currents by a factor of 10 000
over the LM741 A combination 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 compatible with the LM741 allowing an
immediate 10 times reduction in power drain in many appli-
cations The LF441 should be used where low power
