Overview
The KA4558S is a monolithic integrated circuit designed as a dual operational amplifier. It features two independent high-gain amplifiers within a single package, suitable for general-purpose applications. The device operates with a supply voltage span ranging from 4V to 44V and draws a typical supply current of 3.5mA per channel. It supports an operating temperature range of 0°C to 70°C. Key electrical characteristics include a slew rate of 1.2V/s, input bias current of 30nA, and input offset voltage of 2mV.
Feature Summary
- Monolithic dual operational amplifier design
- High gain performance suitable for general usage
- Wide single or split power supply operation
Applications
- General-purpose analog signal processing
- Voltage comparison circuits
- Active filter implementations
Procurement Notes
Verify the specific suffix 'S' indicates the 9-SIP package configuration when sourcing. Confirm the component status, as some listings indicate this part may be discontinued. Ensure the supplier provides official datasheets matching the onsemi specification for the KA4558S variant to guarantee correct pinout and electrical parameters.
Selection Notes
Select this component for applications requiring dual op-amps in a SIP package rather than standard surface-mount formats. Consider the 1.2V/s slew rate and 30nA input bias current for precision requirements. Evaluate if the 9-SIP form factor fits the mechanical constraints of the target design compared to modern SOIC or DIP alternatives.
Part Context
The KA4558S belongs to the broader family of dual operational amplifiers produced by onsemi. It serves as a legacy alternative to newer surface-mount devices, offering a through-hole compatible solution for industrial and commercial equipment. The device maintains compatibility with standard dual op-amp architectures while providing specific packaging advantages for certain assembly processes.
Replacement Considerations
Check for direct pin-compatible replacements such as the LM358 or TL082 series if the KA4558S is unavailable. Verify that substitute parts meet the 44V maximum supply voltage and 3.5mA supply current specifications. Ensure the replacement package matches the 9-SIP requirement or adapt the PCB layout accordingly.
