KA1458D

Overview

The KA1458D is a dual general-purpose operational amplifier manufactured by onsemi, housed in an 8-SOP surface-mount package. It features internal frequency compensation and short-circuit protection. Key electrical parameters include a typical supply current of 2.3mA, a slew rate of 0.5 V/µs, and an input bias current of 80nA. The device operates within a temperature range of 0°C to +70°C.

Feature Summary

• Internal frequency compensation eliminates the need for external components
• Short circuit protection safeguards against output faults
• Wide common mode and differential voltage range enhances flexibility
• Latch-up free operation ensures stable performance

Applications

• Voltage followers
• Integrator circuits
• Summing amplifiers
• General feedback applications

Procurement Notes

Verify the manufacturer origin as Fairchild Semiconductor or its successor entities like onsemi. Confirm the specific 8-SOP package dimensions match the mechanical drawings provided in the datasheet. Ensure the operating temperature range aligns with the 0°C to +70°C specification for the KA1458D variant.

Selection Notes

Select this component for designs requiring low power consumption and high gain without external compensation. It is suitable for applications needing wide input voltage ranges and robust protection features. Consider the 8-SOP package for surface-mount assembly requirements.

Part Context

This part belongs to the KA1458 series of dual operational amplifiers. It shares functional similarities with other industry-standard dual op-amps but is distinguished by its specific package options including 8-DIP, 8-SOP, and 9-SIP. The series is designed for general analog signal processing tasks.

Replacement Considerations

Check pinout compatibility with existing designs. Verify that alternative parts meet the same electrical specifications for offset voltage, bias current, and supply voltage limits.
