BD37515FS-E2

Audio Special Purpose Overview

The BD37515FS-E2 is an audio tone processor IC from ROHM Semiconductor, designed for consumer audio applications. It features a built-in two-band equalizer (Bass and Treble) that requires no external components. The device supports three stereo input sources and provides four independent channel outputs (Front L/R and Rear L/R) with individual volume control. It operates on a single power supply ranging from 7V to 9.5V and utilizes an I2C bus interface for digital control of functions such as volume, tone, mute, and input selection.

Audio Special Purpose Feature Summary

• Built-in 2-band equalizer (Bass/Treble) without external filter components
• 3-input selector supporting multiple music source inputs
• 4-channel independent volume control (Front/Rear L/R)
• I2C bus interface for digital control
• Loudness function interface
• Mute terminal support
• Low noise output (Typ. 3.8 µVrms)

Audio Special Purpose Applications

• Standard home audio equipment
• Consumer audio systems requiring integrated tone processing
• Multi-source audio processors

Audio Special Purpose Procurement Notes

The component is supplied in Tape & Reel (TR) packaging with a standard factory quantity of 2,000 units. Verify the 'E2' suffix against the official datasheet to ensure compliance with current RoHS/REACH standards and pinout configurations. Ensure the host controller supports the I2C protocol required for configuration.
