LC75410WS-E

Audio Special Purpose Overview

The LC75410WS-E is an electronic volume controller manufactured by onsemi, designed for automotive audio applications. It integrates control functions for volume, balance, fader, bass/treble/mid, loudness, input switching, and input gain. The device utilizes a silicon gate CMOS process to minimize switching noise and features an on-chip buffer amplifier to reduce external component count. Control is executed via a serial interface (CCB).

Audio Special Purpose Feature Summary

• On-chip buffer amplifier reduces the number of required external components.
• Low switching noise achieved through silicon gate CMOS process when no signal is present.
• On-chip zero-cross switching circuit minimizes noise during signal operation.
• Integrated 1/2 VDD reference voltage circuit simplifies design.

Audio Special Purpose Applications

• Car audio system volume control
• Audio balance and fader adjustment
• Bass, treble, and midrange tone control
• Loudness compensation circuits
• Input switching and gain management in automotive head units

Audio Special Purpose Procurement Notes

Verify the specific package type (64 SQFP) and pinout configuration against the official datasheet before procurement. Confirm that the serial interface timing requirements match the host microcontroller's capabilities. Ensure thermal management considerations are addressed for the surface mount application within the target operating temperature range.

Audio Special Purpose Selection Notes

Select this component for applications requiring integrated audio control functions with minimal external passive components. Consider the CCB serial interface compatibility with the system controller. Evaluate the power supply voltage range and current consumption against the vehicle's electrical system specifications. Verify the operating temperature range meets the automotive environment requirements.
