Overview
The KA4558S is a dual operational amplifier manufactured by Fairchild Semiconductor. It features a bipolar architecture with voltage-feedback topology and two functional channels within a single package. The device supports a maximum average bias current of 0.8 µA at 25°C and offers a nominal common-mode rejection ratio of 90 dB. It operates with a nominal negative supply voltage of -15 V, with an upper limit of -22 V. The unit is housed in a SIP-9 package containing nine terminals.
Feature Summary
- Dual-channel general-purpose operational amplifier design
- Bipolar voltage-feedback architecture
- Internal frequency compensation for stability
Applications
- General-purpose analog signal processing circuits
- Audio pre-amplification stages
- Sensor signal conditioning
Procurement Notes
Verify the specific suffix 'S' against the manufacturer's official datasheet to confirm the exact pinout configuration and package variant. Ensure compliance requirements are met, as the provided data indicates the component may not be RoHS compliant. Cross-reference the SIP-9 package dimensions with your PCB footprint library to prevent assembly errors.
Selection Notes
Select this component when a dual op-amp solution with bipolar input characteristics is required. Consider the 7500 µV maximum input offset voltage and 0.5 µA bias current specifications for precision applications. Verify that the SIP-9 through-hole package aligns with the target manufacturing process and board layout constraints.
Part Context
This part belongs to the 4558 series of dual operational amplifiers, a standard industry designation for general-purpose analog integrated circuits. Fairchild Semiconductor produced variants of this architecture, utilizing bipolar technology to provide reliable performance in consumer and industrial electronics applications requiring dual amplification functions.
Replacement Considerations
Public confirmed substitute part numbers: RC4558ID (Texas Instruments). TJM4558 (Monolithic Memories) is noted as pin-to-pin compatible with MC1458/LM358 standards.
