KA358ADTF

Overview

The KA358ADTF is a dual operational amplifier manufactured by onsemi. It features two independent, high-gain, internally frequency-compensated amplifiers designed for single-supply operation. The device offers low power consumption with supply current largely independent of voltage. Key electrical characteristics include a large DC voltage gain of 100 dB, a unity-gain bandwidth of 1.1 MHz, and low input bias current of 20 nA. It supports an input common-mode voltage range that includes the negative rail and allows output swing to ground.

Feature Summary

• Internally frequency compensated for stability in standard configurations
• Single-supply operation capability with input common-mode range including ground
• Low power consumption with supply current largely independent of voltage
• High DC voltage gain of 100 dB

Applications

• Sensor signal amplification
• DC gain modules
• Interface electronics for logic systems

Procurement Notes

Verify the manufacturer marking matches onsemi specifications. Confirm the suffix ADTF corresponds to the correct tape-and-reel packaging format. Ensure the part number aligns with the required operating temperature range and package type before finalizing procurement orders.

Selection Notes

Select this component when single-supply operation is required with input signals near ground potential. It is suitable for applications needing moderate bandwidth and high DC gain without external compensation components. Consider thermal performance if multiple units are used in close proximity.

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 by onsemi for reliability and performance within their product portfolio. The ADTF suffix indicates specific packaging and handling requirements.

Replacement Considerations

Compatible replacements include LM358 variants from other manufacturers such as STMicroelectronics or Texas Instruments, provided pinouts and electrical parameters match. Verify compatibility with existing circuit designs before substitution.
