BD37541FS-E2

Audio Special Purpose Overview

The BD37541FS-E2 is a sound processor IC manufactured by ROHM Semiconductor, featuring a built-in 3-band equalizer (Bass, Middle, Treble). It operates on a single power supply ranging from 7V to 9.5V and supports an operating temperature range of -40°C to +85°C. The device features stereo, mono, or zero-channel inputs with selectable configurations. Key electrical parameters include a typical output voltage of 2.2V, total harmonic distortion plus noise (THD+N) of 0.001%, and a quiescent current of 38mA. It utilizes an I2C interface for control and is housed in a 32-SSOP-A package.

Audio Special Purpose Feature Summary

• Integrated 3-band equalizer (Bass, Middle, Treble) for sound quality adjustment
• Supports Stereo 3/1/0 ISO input configurations
• Includes parametric EQ independent of or cascaded from the input selector
• Features 6 outputs with 5-channel fader control

Audio Special Purpose Applications

• Audio equipment utilizing I2C bus control
• General audio tone processing applications

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's latest datasheet before procurement. Confirm that the 32-SSOP-A package dimensions align with the target PCB footprint. Ensure the I2C address configuration matches the system design requirements. Check for any end-of-life notices or recommended replacement parts if availability is constrained.

Audio Special Purpose Selection Notes

Select this component for designs requiring a compact solution with built-in 3-band equalization and parametric EQ capabilities. It is suitable for applications needing up to 6 outputs and 5-channel fader control. Verify that the 7V to 9.5V supply voltage range is compatible with the vehicle's power system. Consider the 38mA quiescent current when calculating overall system power consumption.
