Dual Operational Amplifier
Features
Description

•
•
The LM1458/LM1458C series are dual general purpose
operational amplifiers, having short circuits protected and
require no external components for frequency
compensation. High common mode voltage range and
absence of “latch up" make the LM1458 ideal for use as
voltage followers. The high gain and wide range of operating
voltage provides superior performance in integrator,
summing amplifier and general feedback applications.
Internal frequency compensation
Short circuit protecion
Large common mode and differential voltage range
No latch up
Low power consumption
