Overview
The KA324AD is a quad operational amplifier manufactured by onsemi, housed in a 14-pin MDIP package. It operates within a power supply range of 3 V to 32 V and features four independent circuits. Key electrical parameters include an input offset voltage of 1.5 mV, an input bias current of 250 nA, and a supply current of 1 mA to 1.2 mA. The device provides a voltage gain of 100 dB, a slew rate of 10 V/µs, and a short-circuit protected output capable of sourcing 40 mA per channel. It functions within a commercial temperature range of 0°C to 70°C.
Feature Summary
- Features true differential input stages that allow the common-mode input voltage to include the negative rail, eliminating the need for external bias components in many applications.
- Includes internal frequency compensation and output short-circuit protection to ensure stable operation and device robustness.
- Incorporates input ESD clamps to enhance ruggedness without affecting normal device operation.
Applications
- Transducer amplifiers
- DC gain blocks
- Integrators
Procurement Notes
Verify the specific suffix 'AD' against official datasheets to confirm pinout compatibility and thermal characteristics. Ensure the procurement source provides valid traceability documentation. Confirm that the component meets the required commercial temperature specifications for the intended application environment before finalizing orders.
Selection Notes
Select this component when a quad amplifier with high precision (low input offset voltage) and wide single-supply operation is required. It is suitable for designs needing direct coupling from sensors due to its rail-to-rail input capability. Consider the 14-pin DIP package constraints for PCB layout and thermal management requirements.
Part Context
This part belongs to the LM324/LM224 family of low-power quad operational amplifiers. It shares functional similarities with parts like the LM324ADR2G but differs in packaging and specific parameter tolerances. The KA324AD represents a through-hole variant designed for general-purpose analog signal processing tasks.
Replacement Considerations
The LM324DR2G is a documented substitute offering similar quad amplifier functionality in a surface-mount SOIC-14 package. Verify pinout compatibility and check if the change from DIP to SMD packaging aligns with the target board design requirements.
