Overview
The KA4558STU is a monolithic integrated circuit designed as a dual operational amplifier manufactured by onsemi. It features a 9-SIP package and supports a maximum supply voltage span of 44 V, with individual rails up to ±22 V. The device exhibits an input offset voltage of 2 mV and an input bias current of 500 nA. It is classified under linear amplifiers and instrument op-amps, suitable for general usage applications requiring dual amplifier functionality.
Feature Summary
- Monolithic dual operational amplifier design
- Wide single or dual supply voltage operation
- Low input offset voltage specification
- General-purpose utility configuration
Applications
- General purpose signal conditioning
- Audio pre-amplification stages
- Sensor interface circuits
Procurement Notes
Verify the specific manufacturer source and authenticity when sourcing this component, as it may be listed as obsolete in some distributor catalogs. Confirm the 9-SIP package availability matches your PCB footprint requirements. Ensure the supplier provides valid traceability documentation for quality assurance purposes before finalizing any acquisition.
Selection Notes
Select this part for applications requiring a cost-effective dual op-amp solution with moderate precision. The 9-SIP package is suitable for through-hole mounting. Consider the 2 mV input offset voltage when designing high-gain circuits where drift must be minimized. Verify that the 44 V maximum supply span meets the system power constraints.
Part Context
This component belongs to the broader category of linear integrated circuits produced by onsemi. It serves as a fundamental building block in analog electronics, providing two independent amplification channels within a single package. The device is distinct from single-channel or quad-channel variants, offering a balanced solution for compact dual-amplifier designs.
Replacement Considerations
Check for direct pin-compatible replacements such as the KA4558D in SOIC packages if surface mount is required. Verify electrical parameter equivalence for offset voltage and supply range before substituting.
