KA358A

Overview

The KA358A is a dual operational amplifier manufactured by onsemi, designed for single-supply operation. It features two independent high-gain amplifiers within a single package, optimized for applications requiring low power consumption and wide supply voltage ranges. The device integrates internal frequency compensation to ensure stability in various feedback configurations. It supports common-mode input voltages that include ground, allowing for direct sensing of signals near the negative rail without additional level-shifting circuitry.

Feature Summary

• Dual operational amplifier architecture with independent channels
• Single-supply capability with ground-referenced common-mode input range
• Internal frequency compensation for stable operation across diverse loads

Applications

• Transducer amplifiers
• Active filters
• DC gain blocks

Procurement Notes

Verify the specific suffix codes against the official datasheet to confirm temperature range and packaging options. Ensure compatibility with existing board layouts regarding pinout and thermal dissipation requirements before finalizing procurement decisions.

Selection Notes

Select this component when a dual op-amp solution is required for single-supply systems. Consider its input common-mode range and output swing characteristics relative to the application's signal levels. Evaluate power consumption constraints as it is designed for efficiency in battery-powered or low-power environments.

Part Context

This part belongs to the LM358 family of dual operational amplifiers. It shares functional similarities with other industry-standard dual op-amps but is specifically characterized and manufactured by onsemi. The KA358A variant maintains the core performance metrics expected from this class of analog integrated circuits.

Replacement Considerations

Compatible substitutes include LM358 variants from other manufacturers such as Texas Instruments or NXP Semiconductors. Verify pin-to-pin compatibility and electrical parameter alignment, particularly input offset voltage and slew rate, before implementing any cross-brand replacement.
