BD3818KS

Audio Special Purpose Overview

The BD3818KS is an audio signal processor manufactured by ROHM Semiconductor, designed for consumer audio applications. It features a 6-channel output configuration with integrated volume and tone (Bass/Treble) control functions. The device operates within a supply voltage range of 5V to 7.4V and maintains functionality across an operating temperature range of -20°C to 75°C. Communication with the processor is handled via a serial interface. The component is housed in an 80-SQFP package.

Audio Special Purpose Feature Summary

• Six-channel output configuration with integrated volume and tone control capabilities
• Serial interface for system communication and parameter setting
• Operates on a single power supply ranging from 5V to 7.4V
• Housed in an 80-pin SQFP package suitable for surface-mount technology

Audio Special Purpose Applications

• Consumer audio equipment requiring multi-channel signal processing
• Home theater systems utilizing serial-controlled audio management
• Audio amplifiers integrating tone and volume adjustments

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and RoHS compliance status. Ensure the procurement source provides official documentation matching the 80-SQFP specification. Confirm that the supplied units meet the required electrical parameters for the 5V to 7.4V operating range before integration into production designs.

Audio Special Purpose Selection Notes

Select this component when a design requires six independent output channels controlled via a serial bus. Verify that the available board space accommodates the 80-SQFP footprint. Ensure the system power supply remains stable between 5V and 7.4V to maintain proper operation within the specified -20°C to 75°C temperature envelope.

Audio Special Purpose Part Context

This part belongs to the audio signal processor category, specifically engineered for managing multiple audio outputs in compact consumer electronics. It integrates essential audio processing functions into a single surface-mount package, reducing the need for discrete components typically used for volume and tone control in multi-channel setups.
