LM1458D IC – Dual Operational Amplifier

The LM1458D IC is a dual general-purpose operational amplifier designed for a wide range of analog electronic applications. It integrates two operational amplifier channels in a single IC package, making it suitable for circuit designs requiring multiple amplification stages.

The LM1458 family is designed for general-purpose analog applications and provides wide common-mode and differential voltage ranges, low power consumption and short-circuit protection.

The two internal amplifiers operate independently while sharing a common bias network and power supply connections.
