3 Description

The LF442-MIL dual low power operational amplifiers

provide many of the same AC characteristics as the

industry standard 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-MIL 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 ensures

very low input offset voltage and voltage drift. The

LF442-MIL also has a very low equivalent input noise

voltage for a low power amplifier.

The LF442-MIL is pin compatible with the LM1458

allowing an immediate 10 times reduction in power

drain in many applications. The LF442-MIL should be

used where low power dissipation and good electrical

characteristics are the major considerations.
