BD37524FS-E2

Audio Special Purpose Overview

The BD37524FS-E2 is a sound processor manufactured by ROHM Semiconductor, designed for audio applications requiring tone control and input selection. It features a built-in three-band equalizer (Bass, Middle, Treble) and supports I2C interface control. The device operates within a supply voltage range of 7V to 9.5V and functions reliably across an extended temperature range of -40°C to 85°C. Packaged in a compact SSOP-B28 format, it integrates volume control, fader adjustment, and mute terminals, reducing the need for external components.

Audio Special Purpose Feature Summary

• Built-in 3-band equalizer (Bass, Middle, Treble) with parametric EQ capabilities
• I2C bus interface for digital control of input selection, volume, and tone settings
• 6 output channels including dedicated subwoofer LPF output
• Low current consumption (typical Iq: 38 mA) utilizing BiCMOS process

Audio Special Purpose Applications

• Car audio systems (standard grade, not recommended for harsh automotive environments)
• Home audio receivers and amplifiers
• TV audio processing circuits

Audio Special Purpose Procurement Notes

Verify the specific suffix E2 for RoHS compliance and tape & reel packaging configuration. Confirm the operating temperature range matches the application environment, as the component is rated for -40°C to 85°C. Ensure the design accommodates the 7V to 9.5V supply voltage requirements and utilizes the SSOP-B28 footprint for surface mount assembly.

Audio Special Purpose Selection Notes

Select this component when a compact solution with integrated tone shaping and digital control is required. The BD37524FS-E2 offers a balance of performance and simplicity with its single-chip architecture. Consider the package constraints and ensure the PCB layout supports the thermal dissipation needs for continuous operation at maximum load conditions.

Audio Special Purpose Part Context

This part belongs to ROHM's series of sound processors aimed at simplifying circuit design through software and board commonality. It is positioned as a standard-grade product suitable for applications where extreme automotive ruggedness is not the primary requirement, offering a cost-effective alternative to discrete tone control solutions.
