LMC1983CIN

Audio Special Purpose Overview

The LMC1983CIN is a tone control circuit manufactured by National Semiconductor. It is housed in a 28-pin DIP package with a width of 0.600 inches (15.24mm). The component is designed for through-hole mounting and is supplied in tube packaging. This integrated circuit functions as an audio special purpose device intended for signal conditioning applications.

Audio Special Purpose Feature Summary

• Integrated tone control circuit functionality
• 28-DIP package configuration (0.600 inch / 15.24mm width)
• Through-hole mounting type

Audio Special Purpose Applications

• Audio signal processing circuits
• Tone shaping and equalization systems

Audio Special Purpose Procurement Notes

Verify the manufacturer designation, specifically checking for National Semiconductor or Texas Instruments branding, as ownership transitions occurred. Confirm the 28-DIP physical dimensions match the 0.600-inch specification. Ensure the package style corresponds to tube distribution rather than tape and reel formats.

Audio Special Purpose Selection Notes

Select this component when a dedicated monolithic tone control solution is required for audio paths. The 28-DIP form factor supports standard prototyping boards and legacy chassis designs utilizing through-hole technology. Verify that the specific pinout aligns with the target schematic requirements before integration.

Audio Special Purpose Part Context

This part belongs to the National Semiconductor audio specialty category. It serves as a specialized analog interface component distinct from general-purpose operational amplifiers. The device integrates multiple passive and active elements to manage frequency response characteristics within a single package.
