KA301A

Overview

The KA301A is a general-purpose single operational amplifier manufactured by Fairchild Semiconductor. It features externally phase compensation, allowing for optimized high-frequency performance at selected gains via a single capacitor for unity gain. The device operates within a supply voltage range of ±15V to ±18V and supports an operating temperature range of 0°C to +70°C. Key electrical characteristics include a typical slew rate of 10V/µs as a summing amplifier, a large signal voltage gain of 25 V/mV to 160 V/mV, and a supply current of 2.0 mA at ±15V.

Feature Summary

• Externally phase compensated design allows selection of operation for optimum high-frequency performance at a specific gain using a single capacitor.
• Class AB output stage provides excellent linearity with low bias current.
• Includes short circuit protection and latch-free operation capabilities.

Applications

• Summing amplifier circuits
• General-purpose analog signal processing
• High-frequency applications requiring selectable gain compensation

Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Fairchild Semiconductor Corporation, which has undergone corporate restructuring. Confirm that the specific unit received matches the 8-DIP package and the 0°C to +70°C operating temperature range specified in the datasheet. Ensure the part number corresponds exactly to the KA301A designation without additional suffixes that might alter specifications.

Selection Notes

Select this component when external phase compensation is required to tailor frequency response for specific gain settings. It is suitable for applications needing Class AB output linearity and short-circuit protection. Consider the ±15V to ±18V supply requirement and the 8-DIP package constraint during integration.

Part Context

The KA301A belongs to the family of general-purpose operational amplifiers designed for versatile analog circuit applications. Originally documented under Fairchild Semiconductor, it represents a standard solution for designs requiring adjustable frequency compensation and robust output stages.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation.
