Overview
The KA3403 is a monolithic quad operational amplifier featuring four independent amplifiers with high gain and internal frequency compensation. It supports single supply voltages from 3.0V to 36V or dual supplies of ±1.5V to ±18V. The device includes short-circuit protection and a Class AB output stage for minimal crossover distortion. Operating temperature range is 0°C to +70°C. Electrical characteristics are similar to the KA741, with input common-mode voltage including the negative supply.
Feature Summary
- Internal frequency compensation
- Short circuit protected outputs
- Class AB output stage
Applications
- General purpose analog signal processing
- Single supply applications
- Dual supply applications
Procurement Notes
Verify the specific package type (14-DIP or 14-SOP) required for your design. Confirm the operating temperature range matches your application needs, as the KA3403 is rated for 0°C to +70°C. Ensure the manufacturer source is authorized, as Fairchild Semiconductor products may have been acquired by onsemi. Check datasheet revisions for any updates to electrical parameters.
Selection Notes
Select the KA3403 when general-purpose quad op-amp performance comparable to the UA741 is needed but with improved single-supply operation. Consider the 14-DIP for through-hole mounting or 14-SOP for surface mount. Verify that the input common-mode range including the negative rail meets your circuit requirements without external biasing components.
Part Context
The KA3403 belongs to the KA3303/KA3403 series of quad operational amplifiers originally manufactured by Fairchild Semiconductor. These devices are designed as low-cost alternatives to standard operational amplifiers, offering similar performance to the popular UA741 while providing advantages in single-supply applications due to their wide supply voltage range and input common-mode characteristics.
Replacement Considerations
The KA3303 is the industrial temperature grade (-40°C to +85°C) equivalent within the same series. Other quad op-amps with similar pinouts and electrical characteristics may serve as functional replacements, provided they meet the specific voltage and current requirements.
