KA258D

Overview

The KA258D is a dual operational amplifier manufactured by onsemi. It features a bipolar technology architecture designed for general-purpose applications. The device is housed in an 8-SOIC surface-mount package, providing a compact footprint for circuit integration. It operates within a specified temperature range suitable for commercial and industrial environments.

Feature Summary

• Dual operational amplifier configuration
• Bipolar transistor technology
• Surface-mount 8-SOIC packaging

Applications

• General-purpose signal amplification
• Analog signal processing circuits
• Audio pre-amplifier stages

Procurement Notes

Verify the specific manufacturer source when sourcing this component, as the KA258A designation has been produced by multiple vendors including Fairchild and Samsung. Confirm that the 'D' suffix corresponds to the SOIC-8 package variant from onsemi. Ensure the part status is active before procurement planning, as availability may vary across different supply channels.

Selection Notes

Select the KA258D when a dual op-amp solution in a small surface-mount package is required. Consider its bipolar technology characteristics for offset voltage and bias current specifications relative to other available options. Verify pin compatibility with existing PCB layouts designed for standard 8-pin SOIC footprints.

Part Context

This component belongs to the broader family of dual operational amplifiers. It serves as a surface-mount alternative to through-hole variants like the DIP-8 package. The device is functionally similar to industry-standard dual op-amps, offering two independent amplifiers in a single integrated circuit package for space-constrained designs.

Replacement Considerations

Cross-reference with other dual op-amps in the 8-SOIC package. Verify electrical parameter equivalence for offset voltage and gain bandwidth. Check pinout compatibility to ensure direct replacement without schematic modification.
