KA324

Overview

The KA324 is a quad general-purpose operational amplifier manufactured by Fairchild Semiconductor. It integrates four independent amplifiers within a single package, supporting operation from a single power supply or dual supplies ranging from 3 V to 32 V. Key electrical specifications include a supply current of 1 mA, an output current capability of 40 mA per channel, and a voltage gain of 100 dB. The device features a slew rate of 10 V/µs and operates within a temperature range of 0°C to 70°C. It is housed in a 14-pin DIP package with dimensions of 19.8 mm length, 6.4 mm width, and 5.08 mm height.

Feature Summary

• Supports flexible power configurations with wide single or dual supply voltage ranges
• Provides high output drive capability suitable for interfacing with various loads

Applications

• DC gain blocks
• Audio pre-amplifiers
• Transducer amplifiers

Procurement Notes

Verify the specific manufacturer marking and date code against official Fairchild Semiconductor documentation to confirm authenticity. Ensure the component matches the specified 14-DIP physical dimensions and pinout configuration. Check for lead-free compliance status if required by your assembly process standards.

Selection Notes

Select this component when multiple low-power operational amplifiers are needed in a compact through-hole footprint. It is suitable for applications requiring wide supply voltage flexibility and moderate output current without the need for complex external biasing networks.

Part Context
