BD3433K-E2

Overview

The BD3433K-E2 is a 6-channel audio processor and volume controller manufactured by ROHM Semiconductor. It operates within a supply voltage range of 7V to 9.5V and features a serial interface for control. The device is housed in a 44-QFP (10x10mm) surface-mount package and supports an operating temperature range of -40°C to +85°C. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of 0.001% and a power output capability of 850 mW per channel. The unit draws a typical operating current of 10 mA.

Feature Summary

• Six independent audio channels with integrated volume control
• Serial interface for digital control and configuration
• Low distortion performance with THD+N of 0.001%
• UL94 V-0 flame classification for the mold compound

Applications

• Audio/Visual equipment
• Office automation devices
• Consumer communication systems
• Gaming and entertainment sets

Procurement Notes

Verify component authenticity through authorized ROHM distributors or direct sales channels. Confirm that the specific revision matches the required UL94 V-0 classification if fire safety standards are critical for the enclosure design. Ensure the serial interface timing requirements align with the host microcontroller capabilities before finalizing the bill of materials.

Selection Notes

Select this component when a multi-channel audio processing solution with low distortion is required. The 7V to 9.5V supply range dictates the power architecture of the target system. The 44-QFP package requires adequate PCB real estate for the 10x10mm footprint. Verify that the serial protocol compatibility exists between the controller and the BD3433K-E2.
