LM1458/LM1458C

Dual Operational Amplifier

Features		Description
•	Internal frequency compensation	The LM1458/LM1458C series are dual general purpose
•	Short circuit protecion	operational	amplifiers, having short circuits protected and
• Large common mode and differential voltage range		require no	external components for frequency
•	No latch up	compensation. High common mode voltage range and
•	Low power consumption	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.
