KA324ADTF

Overview

The KA324ADTF is a quad operational amplifier manufactured by Fairchild Semiconductor. It features four independent high-gain amplifiers within a single package, designed for general-purpose analog signal processing applications. The device operates with a wide supply voltage range of 3 V to 32 V or ±1.5 V to ±16 V. Key electrical specifications include an input bias current of 40 nA, an input offset voltage of 1500 µV, and a supply current of 1 mA per channel. Each output can deliver up to 40 mA. The component is rated for operation within a temperature range of 0°C to 70°C and is available in a 14-DIP (0.300 inch) through-hole package.

Feature Summary

• Integrates four independent operational amplifiers for multi-channel signal conditioning
• Supports wide single or dual power supply voltage ranges
• Provides high output drive capability suitable for various loads

Applications

• General-purpose analog signal amplification
• DC gain blocks in instrumentation circuits
• Active filter designs

Procurement Notes

Verify the manufacturer marking and date code against official Fairchild Semiconductor documentation to ensure authenticity. Confirm that the part number suffix matches the specific package variant required for your design. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the operating temperature range meets your system's thermal requirements.

Selection Notes

Select this component when multiple independent amplification stages are needed in a compact form factor. Consider the input offset voltage and bias current specifications for precision requirements. Verify that the supply voltage range aligns with your system's power rails. Evaluate the DIP package constraints against your PCB layout capabilities.

Part Context

The KA324 series belongs to the family of quad operational amplifiers widely used in industrial and consumer electronics. Fairchild Semiconductor produced these devices as cost-effective solutions for basic analog functions. The ADTF suffix typically denotes a specific tape-and-reel packaging option for surface-mount or automated assembly processes, distinct from standard tube packaging.

Replacement Considerations

Compatible substitutes include LM324 variants from other manufacturers such as STMicroelectronics or Texas Instruments. Verify pin compatibility and electrical parameter equivalence before substitution. Ensure the replacement part supports the same supply voltage range and package dimensions.
