BD37542FS-E2

Audio Special Purpose Overview

The BD37542FS-E2 is a three-channel audio tone processor manufactured by ROHM Semiconductor, housed in a 32-lead SSOP-A package. It operates on a supply voltage range of 7 V to 9.5 V with a typical quiescent current of 38 mA. The device features a built-in three-band equalizer (Bass, Mid, Treble) for sound quality adjustment, alongside volume and fader controls. The component supports I2C bus communication for configuration and functions within an operating temperature range of -40°C to +85°C.

Audio Special Purpose Feature Summary

• Integrated three-band equalizer (Bass, Middle, Treble) for sound quality adjustment
• Three output channels with independent volume and fader controls
• I2C bus interface for digital control of gain, input selection, and EQ parameters
• Supports common control software to increase design efficiency

Audio Special Purpose Applications

• Automotive audio systems requiring integrated tone processing
• Home audio equipment needing multi-channel volume and balance control
• Sound processors utilizing parametric equalization via cascade connection

Audio Special Purpose Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm RoHS compliance and lead-free status. Confirm that the 32-SSOP-A package dimensions match the target PCB footprint. Ensure the I2C address configuration aligns with the system design requirements before procurement.

Audio Special Purpose Selection Notes

Select this component when a three-channel audio processor with built-in three-band EQ is required. It is suitable for designs needing I2C control over volume, fader, and input mixing. Compare the 7 V to 9.5 V supply requirement against the system power rail. Consider the 38 mA quiescent current for power budget calculations.
