KA358D

Overview

The KA358D is a dual general-purpose operational amplifier manufactured by onsemi. It features two independent high-gain amplifiers within a single package, designed for versatile analog signal processing applications. The device operates with a wide supply voltage range, supporting dual supplies from ±1.5 V to ±8 V (±16 V total) or single supplies up to 32 V. It utilizes an 8-pin SOIC surface-mount package, ensuring compatibility with standard PCB layouts. Key electrical characteristics include a maximum input offset voltage of 7 mV and an input bias current of 150 nA, providing stable performance across the specified operating temperature range of 0°C to 70°C.

• Active filter implementations

Procurement Notes

Verify the specific manufacturer part number against official onsemi documentation to confirm pinout and electrical specifications. Ensure the procurement source provides valid traceability data. Confirm that the delivered components match the 8-SOIC package type and intended industrial temperature range requirements before integration into production designs.

Selection Notes

Select this component when a cost-effective dual operational amplifier is required for general-purpose applications. Consider the 8-SOIC package constraints for board space. Evaluate the 7 mV input offset voltage specification against the precision requirements of the target circuit to ensure adequate accuracy for the intended signal processing task.

Part Context

This component belongs to the broader family of dual operational amplifiers offered by onsemi. It serves as a standard solution for basic amplification tasks where high precision is not the primary constraint. The device complements other linear ICs in the manufacturer's portfolio, offering a balance between performance and manufacturability for mass-market electronic devices.

Replacement Considerations

Cross-reference with LM358DR2G or LM358DMR2G for functional equivalents. Verify pin compatibility and electrical parameter alignment before substitution. Ensure the alternative package type matches the existing PCB footprint design constraints.
