KA741

Overview

The onsemi KA741 is a general-purpose operational amplifier manufactured by Fairchild Semiconductor. It features short circuit protection, excellent temperature stability, and internal frequency compensation. The device supports an input voltage range of ±13 V and operates with supply voltages up to ±18 V. Electrical characteristics include a typical slew rate of 0.5 V/µs, input bias current of 80 nA, and output short circuit current of 25 mA. It is available in 8-DIP and 8-SOP packages.

Feature Summary

Internal frequency compensation ensures stability in closed-loop circuits without external components.
Short circuit protection allows indefinite duration during output shorting events.
High input voltage range accommodates wide signal swings relative to supply rails.

Applications

Integrator circuits
Summing amplifiers
General feedback applications

Procurement Notes

Verify the specific suffix (e.g., KA741I) for extended temperature ranges (-40°C to +85°C). Confirm package type availability as the standard KA741 is listed as obsolete. Ensure sourcing from authorized distributors to validate component authenticity and traceability.

Selection Notes

Select this component for general analog applications requiring high gain and wide operating voltage ranges. Consider the KA741I variant if operation below 0°C is required. Verify that the bipolar technology and offset voltage specifications meet the precision requirements of the target design.

Part Context

Originally produced by Fairchild Semiconductor Corporation, the KA741 belongs to the widely recognized 741 series of operational amplifiers. This family established standards for general-purpose analog signal processing. The device utilizes bipolar technology and is designed for robust performance in various industrial and commercial electronic systems.

Replacement Considerations

Texas Instruments UA741CP is documented as a direct substitute. LM741CN/NOPB is also listed as a similar alternative. Verify pinout compatibility and electrical parameter alignment before implementation.
