LC75411UES-E

Audio Special Purpose Overview

The LC75411UES-E is an electronic volume controller IC manufactured by onsemi. It is designed for use in car audio systems to control volume, balance, fader, tone (bass/treble), loudness, and input selection. The device features a serial interface (CCB) for control signals and includes internal buffer amplifiers to simplify the external circuit design.

Audio Special Purpose Feature Summary

• Electronic volume control with balance, fader, and tone adjustment capabilities
• Serial control interface (CCB) for connection to microcontrollers or remote controls
• On-chip buffer amplifiers reduce the number of required external components
• Silicon gate CMOS process technology for low power consumption and noise reduction
• Zero-cross switching function to minimize popping noise during signal transitions

Audio Special Purpose Applications

• Car audio system main unit volume controllers
• Automotive audio balance and fader circuits
• Tone control sections in automotive head units
• Input source switching logic in car stereos

Audio Special Purpose Procurement Notes

Verify the 'UES' suffix specifically denotes the 44-pin QFP package variant as per the official datasheet. Ensure compliance with automotive environmental standards if the application requires AEC-Q100 qualification or specific temperature ranges beyond standard industrial specs.

Audio Special Purpose Selection Notes

Select this component for integrated audio front-end designs where board space is limited. The built-in buffers eliminate the need for external operational amplifiers for basic volume/balance functions. Confirm that the host MCU supports the CCB serial protocol timing requirements.
