Overview
The KA358DTF is a dual operational amplifier manufactured by Fairchild Semiconductor. It features two independent, high-gain, internally frequency-compensated amplifiers within a single package. The device operates on a supply voltage span ranging from 3 V to 32 V and supports an operating temperature range of 0°C to 70°C. It utilizes a surface mount mounting type for integration into electronic circuits.
Feature Summary
- Dual independent operational amplifier configuration
- Internally frequency compensated for stability
- High gain performance characteristics
Applications
- General-purpose analog signal processing
- Motor control cabinet installations
- Industrial control systems
Procurement Notes
Verify the manufacturer origin as Fairchild Semiconductor or its successor entities. Confirm the specific suffix DT indicates the correct surface-mount package variant. Ensure compliance with RoHS standards if required by the target application environment. Cross-reference part numbers carefully to distinguish between legacy Fairchild branding and current ownership structures.
Selection Notes
Select this component when a dual op-amp solution is required for general-purpose applications. The internal frequency compensation simplifies circuit design by reducing external component requirements. Verify that the supply voltage range of 3 V to 32 V aligns with the system power rails. Consider the industrial temperature range suitability for the intended deployment environment.
Part Context
The KA358 series consists of dual operational amplifiers similar in function to the LM358 family. Fairchild Semiconductor produced these components before industry consolidation. The KA358DTF represents the surface-mount version of this widely used analog integrated circuit. It serves as a standard component for various linear and non-linear applications.
Replacement Considerations
The LM358D is a comparable alternative offering similar functional specifications. Verify pin compatibility and electrical parameters before substitution. Ensure the replacement meets the same temperature and voltage requirements.
