KA741D

Overview

The onsemi KA741D is a general-purpose operational amplifier manufactured using bipolar technology, housed in an 8-SOP surface-mount package. It features internal frequency compensation and operates within a temperature range of 0°C to +70°C. Key electrical specifications include a maximum input offset voltage of 6.0 mV (with RS ≤ 10kΩ), a typical supply current of 1.5 mA at ±15 V, and a slew rate of 0.5 V/µs. The device supports a supply voltage of up to ±18 V and provides short circuit protection.

Feature Summary

Internal frequency compensation eliminates the need for external components
Built-in short circuit protection ensures indefinite duration safety
Capable of nulling input offset voltage via dedicated adjustment terminals

Applications

Integrator circuits
Summing amplifiers
General feedback applications

Procurement Notes

Verify that the specific KA741D suffix corresponds to the 8-SOP package variant rather than the standard 8-DIP version. Confirm the operating temperature grade matches the required 0°C to +70°C specification. Ensure the design accommodates the bipolar process characteristics and absolute maximum ratings defined in the datasheet.

Selection Notes

Select this component when a surface-mount solution is required for general-purpose analog signal processing. The 8-SOP package facilitates automated assembly compared to through-hole alternatives. Consider the 0°C to +70°C industrial temperature range suitability for the target environment before finalizing the design.

Part Context

The KA741 series represents a classic single operational amplifier architecture originally developed by Fairchild Semiconductor. This specific part number denotes the surface-mount SOP variant of the widely recognized 741 topology. It maintains the functional compatibility of the original design while adapting to modern PCB mounting requirements.

Replacement Considerations

Direct substitutes include the KA741 (8-DIP) for through-hole designs or other 741-compatible op-amps from various manufacturers. Verify pinout compatibility and package dimensions when transitioning between DIP and SOP formats.
