LF442

Dual Low Power JFET Input Operational Amplifier

General Description

The LF442 dual low power operational amplifiers provide

many of the same AC characteristics as the industry stan-

dard LM1458 while greatly improving the DC characteristics

of the LM1458. The amplifiers have the same bandwidth,

slew rate, and gain (10 kΩ load) as the LM1458 and only

draw one tenth the supply current of the LM1458. In addition

the well matched high voltage JFET input devices of the

LF442 reduce the input bias and offset currents by a factor of

10,000 over the LM1458. A combination of careful layout

design and internal trimming guarantees very low input offset

voltage and voltage drift. The LF442 also has a very low

equivalent input noise voltage for a low power amplifier.

The LF442 is pin compatible with the LM1458 allowing an

immediate 10 times reduction in power drain in many appli-

cations. The LF442 should be used where low power dissi-

pation and good electrical characteristics are the major con-

siderations.
