BD3403FV-E2

Overview

The BD3403FV-E2 is a stereo audio signal processor manufactured by ROHM Semiconductor, designed for consumer audio applications. It operates within a supply voltage range of 6.5 V to 9.5 V and draws a typical quiescent current of 16 mA. The device features a 40-pin SSOP-B package and supports serial interface control. Key electrical parameters include an input gain range of +26 dB to 0 dB with digital switching capability. It integrates tone control functions for bass, middle, and treble bands, providing comprehensive sound processing capabilities in a compact surface-mount form factor.

Feature Summary

• Integrated 3-band tone control (bass, middle, treble) for stereo audio signals
• Serial interface control with adjustable input gain from +26 dB to 0 dB
• Low power consumption with 16 mA operating current at 6.5 V–9.5 V supply
• 40-lead SSOP-B package suitable for space-constrained designs

Applications

• Consumer audio equipment requiring integrated sound processing
• Stereo systems needing built-in equalization controls
• Audio devices utilizing serial interface for volume and tone adjustment

Procurement Notes

Verify the component status as End-of-Life (EOL) before procurement planning. Confirm that the ordering suffix -E2 corresponds to the specific RoHS-compliant variant documented in official ROHM datasheets. Ensure compatibility with existing serial communication protocols in the target design.

Selection Notes

Select this component when a stereo audio processor with integrated 3-band equalization is required. Verify that the system supply voltage remains within the 6.5 V to 9.5 V range to ensure proper operation. Consider the 40-SSOP-B package dimensions for PCB layout constraints and confirm thermal performance within the -25°C to 75°C operating temperature range.

Part Context

The BD3403FV-E2 belongs to the BD3403FV series of audio signal processors from ROHM Semiconductor. It is specifically identified as an End-of-Life product, indicating it is no longer recommended for new designs. The -E2 suffix typically denotes environmental compliance variations, such as RoHS adherence, consistent with manufacturer naming conventions.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Designers should consult ROHM's official replacement guide or contact the manufacturer for qualified alternatives due to the End-of-Life status.
