LM1458N Dual Operational Amplifier
The LM1458N is a versatile and reliable general-purpose dual operational amplifier. It integrates two independent, high-gain operational amplifiers in a single package. The two amplifiers share a common bias network and power supply leads, but otherwise, their operation is completely independent. Known for its durability, the LM1458N features short-circuit protection and does not require external components for frequency compensation, simplifying circuit design. Its wide common-mode voltage range and resistance to latch-up make it an excellent choice for use as a voltage follower.
Features
- No Frequency Compensation Required
- Short-Circuit Protection
- Wide Common-Mode and Differential Voltage Ranges
- Low-Power Consumption
- No Latch-Up
