BD37511FS-E2

Audio Special Purpose Overview

The BD37511FS-E2 is a sound processor manufactured by ROHM Semiconductor, housed in a 20-pin SSOP-A package. It operates on a single power supply ranging from 7 V to 9.5 V with a typical operating current of 15 mA. The device integrates four independent channels for volume control and includes built-in bass and treble tone controls accessible via an I2C bus interface. Key electrical specifications include a maximum output power of 940 mW and a total harmonic distortion plus noise (THD+N) of 0.005%.

Audio Special Purpose Feature Summary

• Integrates 4-channel independent volume control and 2-band (bass/treble) tone processing
• Controlled via I2C bus interface for digital adjustment of audio parameters
• Low THD+N of 0.005% ensures high-fidelity audio signal processing
• Operates within a 7 V to 9.5 V single-supply voltage range
• Built-in 3-input selector supporting front/rear L/R outputs

Audio Special Purpose Applications

• Consumer electronics requiring integrated tone and volume management
• Systems utilizing I2C-controlled audio signal chains
• Standard-type home audio equipment (Not recommended for automotive use)

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm pinout and functional compatibility. Ensure the design supports the required I2C communication protocol and that the supply voltage remains within the 7 V to 9.5 V operational window. Confirm RoHS compliance status through official documentation prior to integration. Note: This part is not recommended for automotive applications.

Audio Special Purpose Selection Notes

Select this component when a compact solution for multi-channel volume and tone adjustment is needed without external discrete components. The I2C interface allows for flexible software-defined audio tuning. Ensure the application environment stays within the specified -40°C to +85°C temperature range and that the PCB layout accommodates the SSOP-20 footprint.
