KA358STU

Overview

The KA358STU is a dual operational amplifier manufactured by Fairchild Semiconductor. It consists of two independent, high-gain, internally frequency-compensated amplifiers designed for single power supply operation over a wide voltage range. The device features a large DC voltage gain and an input common-mode voltage range that includes ground. It supports split power supplies and maintains low power supply current drain independent of the supply voltage magnitude.

Feature Summary

• Internally frequency compensated for unity gain stability
• Wide power supply range capability
• Input common-mode voltage includes ground potential
• Low power supply current drain suitable for battery operation

Applications

• Transducer amplifier circuits
• DC gain blocks
• Conventional operational amplifier circuits in single power supply systems

Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or its successors, noting corporate acquisitions may affect branding. Confirm the package type matches the STU suffix specifications. Ensure the component meets required electrical parameters for gain and supply voltage ranges before integration into designs.

Selection Notes

Select this component when designing circuits requiring dual operational amplifiers with internal frequency compensation. It is suitable for applications needing a wide power supply range and ground-referenced inputs. Consider its low power consumption characteristics for battery-powered systems requiring stable DC gain.

Part Context

This part belongs to the family of low-power dual operational amplifiers, sharing functional similarities with the LM358 series. These devices are engineered for general-purpose analog signal processing tasks where single-supply operation and cost-effectiveness are primary design constraints.
