KA358A-T

Overview

The KA358A-T is a dual operational amplifier manufactured by onsemi, featuring two independent high-gain amplifiers within a single package. It operates with a supply voltage range of 3 V to 32 V or ±1.5 V to ±16 V. Key electrical parameters include a gain-bandwidth product of 20 kHz, a slew rate of 3 V/µs, and an input offset voltage of 7 mV. The device draws 1.2 mA of operating current and provides a typical output short-circuit current of 30 mA per channel. It offers a common-mode rejection ratio of 65 dB and functions within a temperature range of 0°C to +70°C.

Feature Summary

• Dual-channel architecture providing two independent high-gain amplifiers in a compact form factor
• Wide single-supply operation capability supporting voltages up to 32 V
• Internal frequency compensation eliminates the need for external components
• Common-mode input voltage range includes ground potential

Applications

• Transducer amplifiers
• Active filters
• DC gain blocks

Procurement Notes

Verify component authenticity through authorized distribution channels due to the availability of counterfeits in the market. Confirm that the specific suffix matches the required package type, as variations exist between tape-and-reel and cut-tape formats. Ensure compliance with RoHS directives if environmental standards are mandatory for the assembly process. Check for lead-free solderability requirements prior to integration into the manufacturing line.

Selection Notes

Select this component when a general-purpose dual op-amp is required for low-frequency signal conditioning applications. It is suitable for designs needing wide single-supply voltage tolerance and internal frequency compensation. Consider alternative parts if higher bandwidth or lower power consumption is critical, as this device prioritizes versatility over high-speed performance metrics.

Part Context

The KA358A belongs to the KA358A series of dual operational amplifiers produced by onsemi. This series is designed for general-purpose analog signal processing tasks. The device utilizes standard SOIC-8 packaging for surface-mount installation, facilitating easy integration into printed circuit boards requiring minimal footprint space for dual-channel amplification needs.

Replacement Considerations

The LM358ADR2G is listed as a manufacturer-recommended substitute for the KA358A-T. Verify pinout compatibility and electrical parameter equivalence before swapping components in existing designs.
