LC75410NES-E

Overview

The LC75410NES-E is a CMOS electronic volume controller designed for car audio systems. It integrates control functions for volume, balance, fader, bass/treble/mid, loudness, input switching, and input gain using minimal external components. The device features an on-chip buffer amplifier to reduce component count and utilizes a silicon gate CMOS process to minimize switching noise. Key technical attributes include low switching noise during signal absence due to the CMOS process, reduced noise during signal presence via an on-chip zero-cross switching circuit, and an integrated 1/2 VDD reference voltage circuit. Control operations are executed through serial input using the CCB protocol.

Feature Summary

• Integrates comprehensive audio control functions including volume, balance, fader, tone adjustment, and input selection within a single chip.
• Employs a silicon gate CMOS process to achieve low switching noise when no audio signal is present.
• Incorporates an on-chip zero-cross switching circuit to minimize audible switching noise during active signal playback.
• Features an internal buffer amplifier that reduces the requirement for external supporting components.

Applications

• Car audio system volume and tone control
• Automotive multimedia interface modules
• Vehicle infotainment input switching circuits

Procurement Notes
