KA324DTF

Overview

The KA324DTF is a quad operational amplifier manufactured by onsemi, housed in a 14-pin DIP package. It features four independent amplifiers per package with true differential inputs and short-circuit protected outputs. The device operates on single supplies ranging from 3 V to 32 V. Key electrical parameters include an input bias current of 250 nA, an input offset voltage of 7 mV, and a supply current of 1 mA. It provides a voltage gain of 100 dB and a slew rate of 10 V/µs. The component supports through-hole mounting and functions within a commercial temperature range of 0°C to 70°C.

Feature Summary

• Single supply operation capability spanning 3.0 V to 32 V
• True differential input stage with common mode range extending to the negative supply
• Short-circuited protected outputs for enhanced reliability
• Internally compensated design eliminating external compensation components

Applications

• Transducer amplifiers
• DC gain blocks
• Integrators

Procurement Notes

Verify the specific suffix 'DTF' against official datasheets to confirm pinout compatibility and package dimensions. Ensure the operating environment remains within the specified commercial temperature limits. Confirm lead-free compliance status if required by assembly standards. Cross-reference ordering information directly with onsemi documentation to avoid substitution errors.

Selection Notes

Select this component for applications requiring multiple amplifiers in a single package with low power consumption. The wide single-supply voltage range suits battery-powered or variable voltage systems. Verify that the input bias current and offset voltage meet circuit precision requirements. Consider the DIP package constraints for PCB layout and thermal management during selection.

Part Context

The KA324 series belongs to a family of low-cost quad operational amplifiers designed for general-purpose analog signal processing. These devices offer distinct advantages over standard types in single-supply applications due to their ability to handle input signals down to the negative rail. The series includes variants like LM324 and LM324A, providing options for different performance levels while maintaining industry-standard pinouts.

Replacement Considerations

Compatible substitutes include LM324, LM324A, LM224, and NCV2902. Verify pinout compatibility and electrical parameter tolerances before substitution. Automotive-grade variants may require specific prefix verification.
