Overview
The BD37510STU is a sound processor IC from ROHM Semiconductor, designed for audio applications. It features a built-in two-band equalizer (bass and treble) with filters that require no external components. The device supports three stereo input channels and provides four independent channel outputs. Control is managed via an I2C bus interface, allowing for digital adjustment of volume and tone settings. It operates within a supply voltage range of 7V to 9.5V and consumes a typical current of 15mA.
Feature Summary
- Integrated two-band equalizer for bass and treble control without external filter components
- I2C bus interface for digital control of volume and tone parameters
- Supports three stereo inputs and four independent output channels
- Designed for standard home audio equipment with reduced external component count
Applications
- Standard home audio receivers
- Audio amplifiers requiring integrated tone control
- Sound processors in consumer electronics
Procurement Notes
Verify the manufacturer designation carefully, as the model BD37510STU is primarily associated with ROHM Semiconductor rather than onsemi. Confirm the specific suffix 'STU' against official ROHM documentation to ensure correct package type and tape/reel specifications. Cross-reference part numbers with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when a compact solution for multi-channel audio processing with integrated equalization is required. The I2C interface simplifies system integration by reducing pin count compared to parallel control schemes. Ensure the application environment stays within the specified temperature range and does not involve automotive conditions, as the product is not qualified for such use.
Part Context
This component belongs to a series of sound processors aimed at standardizing control software and circuit boards across different audio products. The series emphasizes high performance with minimal external parts, facilitating space-saving designs for standard home audio equipment. It serves as a specialized audio IC distinct from general-purpose microcontrollers or power management devices.
