LF442 Datasheet (National Semiconductor) - Dual Low Power JFET Input Operational Amplifier

LF442, Dual Low Power JFET Input Operational Amplifier

The LF442 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
