Overview
The BD3843FS-E2 is a stereo audio sound processor manufactured by ROHM Semiconductor, housed in an SSOP-A24 package. It operates on dual power supplies ranging from ±5V to ±7.3V (10V to 14.6V total) or single sources within compatible limits. The device features six output channels and supports two-line serial control bus interfaces for both 3.3V and 5V logic levels. Key electrical specifications include a quiescent current of 3mA, a typical output voltage of 4.2V, and a THD+N of 0.004%. It functions as a volume LSI capable of simultaneous control with other models like the BD3813KS.
Feature Summary
- Supports 2-room entertainment and 2-source recording configurations
- Enables simultaneous control with 6ch volume LSIs via serial bus
- Features excellent cross-talk characteristics through original pattern layout
- Includes built-in buffer amplifiers for signal integrity
Applications
- Multi-zone home audio systems requiring independent zone control
- Audio processors integrating multiple source inputs
- Stereo sound processing units with serial interface requirements
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications, as this specific variant may have limited availability. Ensure ordering suffixes match exact package and tape specifications required for your assembly process.
Selection Notes
Select this component when designing stereo audio systems requiring six outputs and serial bus compatibility. Verify that the dual power supply range of ±5V to ±7.3V aligns with your system architecture. Consider its integration capabilities with BD3813KS or BD3815KS if multi-zone functionality is needed.
Part Context
This part belongs to ROHM's audio processor family, specifically designed for volume control and sound processing applications. It complements other series members like the BD3841FS and BD3813KS, allowing for scalable audio architectures. The SSOP-A24 package facilitates surface-mount assembly in compact consumer electronics designs.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official ROHM resources for pin-compatible alternatives or updated lifecycle recommendations before finalizing designs.
