BD37514FS-E2

Audio Special Purpose Overview

The BD37514FS-E2 is a sound processor IC from ROHM Semiconductor, featuring a built-in 2-band equalizer (Bass, Treble). It operates on a single power supply of 7V to 9.5V with a typical quiescent current of 38 mA. The device integrates volume control, fader, mute, and loudness functions, all controllable via an I2C interface. It supports multiple input selections and provides five output channels with a THD+N of 0.001% and output noise of 3.8 µVrms. It operates within a temperature range of -40°C to +85°C.
