BD3813KS-E2

Overview

The BD3813KS-E2 is a 6-channel audio signal processor manufactured by ROHM Semiconductor. It operates on a single supply voltage ranging from 5V to 7.3V and draws a typical quiescent current of 10 mA. The device features 6 inputs, 6 outputs, and integrated tone controls for bass and treble adjustment. It utilizes a serial interface for control and is housed in a 56-SQFP (10x10) surface-mount package. The component supports independent volume and fader adjustments across all channels.

Feature Summary

• 6-channel input and output configuration
• Integrated bass and treble tone control
• Serial interface for digital control
• Single supply operation (5V to 7.3V)

Applications

• Consumer audio equipment
• Multi-channel sound processing systems

Procurement Notes

This component is designated as End-of-Life (EOL). Verification of availability should focus on existing stock or last-time buy opportunities. Ensure compatibility with the 56-SQFP footprint during sourcing.

Selection Notes

Select this part for applications requiring 6-channel audio processing with basic tone control. Verify that the system design accommodates the 56-SQFP package dimensions and the 5V-7.3V power supply range. Confirm serial interface protocol compatibility.

Part Context

The BD3813KS-E2 belongs to the BD3813KS series of audio processors. It provides multi-channel signal management within a compact surface-mount form factor, suitable for space-constrained consumer electronics designs requiring integrated audio control functions.

Replacement Considerations

Due to the EOL status, direct substitutes may be limited. Review ROHM's newer audio processor families for potential pin-compatible or functionally equivalent alternatives.
