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.
