Overview
The KA258ADTF is a dual general-purpose operational amplifier manufactured by Fairchild Semiconductor. It integrates two independent, high-gain, internally frequency-compensated circuits within an 8-SOIC package. The device operates on a supply voltage range of 3 V to 32 V or ±1.5 V to ±16 V. Key electrical specifications include a typical input bias current of 40 nA, an input offset voltage of 1 mV, and a channel output current capability of 30 mA. The operating supply current is specified at 800 μA.
Feature Summary
- Dual circuit configuration with internal frequency compensation for stability
- High gain performance suitable for analog signal processing
- Wide single or dual supply voltage operation range
Applications
- General purpose analog signal processing
- Active filter designs
- Voltage follower configurations
Procurement Notes
Verify the manufacturer marking matches Fairchild Semiconductor or ON Semiconductor branding. Confirm the suffix 'ADTF' indicates the specific tape-and-reel packaging variant if required by assembly equipment. Ensure the component lot date code aligns with project requirements. Cross-reference the datasheet revision to confirm pinout compatibility with existing PCB layouts.
Selection Notes
Select this component when a dual op-amp solution is required with low input bias current characteristics. The wide supply voltage range supports both single-supply and split-rail systems. Verify that the 8-SOIC package fits the available board space and thermal constraints. Consider the 30 mA output drive capability against load requirements.
Part Context
This part belongs to the KA258 series of operational amplifiers. The series is characterized by bipolar technology and general-purpose design. It serves as a standard linear amplifier IC for various electronic applications requiring dual-channel amplification.
Replacement Considerations
Check for direct pin-compatible substitutes from other manufacturers such as LM358 variants. Verify electrical parameters like input offset voltage and bandwidth match application needs before substitution.
